Simple math is used to determine a person’s body mass index using their height and weight. BMI is calculated as follows: kg = weight in kilograms/m2, where m2 equals height in meters squared.
Overweight is defined as a BMI of 25.0 or higher, while a healthy range is 18.5 to 24.9. Most persons between the ages of 18 and 65 have BMI.

Find out what your BMI is (BMI) A measurement of body fat based on height and weight is called the body mass index, or BMI.
Pounds and inches can be used to compute it: BMI = (weight in pounds x 703) / (height in inches x height in inches).
Alternately, you might use the calculator below:
You can be a candidate for weight loss surgery if you have a BMI of 40 or higher, or if your BMI is between 35 and 39.9 and you also have an obesity-related medical condition such diabetes, high blood pressure, or sleep apnea.

The Body Mass Index (BMI) Calculator can be used to determine a person’s age-adjusted BMI and corresponding weight status. To convert units into either US or metric units, use the “Other Units” option or the “Metric Units” tab for the International System of Units. Notably, the calculator also determines the Ponderal Index in addition to BMI; these are covered in more detail below.
BMI =
Women who are pregnant or nursing should not use this calculator, and no decisions should be made based on the results other than to consult a professional who is appropriately qualified, such as a doctor.
You may get a sense of how your weight stacks up against standard weights with the calculator. The formula for calculating body mass index, or BMI, is weight in kilograms divided by height in meters squared, or Kg/M2.
Body mass index (BMI) definition
A medical screening tool called the body mass index (BMI) calculates the ratio of your height to weight to determine how much body fat you have. BMI is calculated by medical professionals by dividing weight in kilograms (kg) by the square of height in meters (m2).
The majority of the time, a person’s BMI correlates to their body fat; the higher the figure, the more body fat you may have, although this isn’t always the case. BMI is not a diagnostic tool for health. BMI and other tools and tests are used by medical professionals to evaluate a patient’s health and risk factors.
Heart disease, stroke, and Type 2 diabetes may be brought on by high body fat. Malnutrition may be linked to low body fat. The proper quantity of body fat aids in the absorption of vitamins and minerals. It also gives your body a source of energy, aids in regulating body temperature, and shields your organs.
The typical BMI chart should not be used to determine a child’s or teen’s weight. Find out from your child’s doctor what weight is best for their height and age.
How can I figure out my BMI by hand?
It is necessary to convert fractions and ounces (oz) to decimal numbers when using English measures. Then, multiply the result by a conversion factor of 703, which is the product of the weight in pounds (lb) and the height in inches (in) squared.
- If your handheld calculator includes a square function, divide your weight (lb) by your height (in) squared, multiply by 703, and round to the nearest whole number.
Let’s use the English number system to get Sam’s BMI. He stands 41 1/2 inches tall and weighs 37 pounds, 4 ounces.
- Calculation 1: Georgia is 39 inches tall and weighs 36 1/2 pounds. What is the BMI in Georgia? Show me the solution.
- Second calculation: Jose is 40 1/4 pounds and 40 3/4 inches tall. Jose’s BMI is what? Show me the solution.
When comparing BMI calculations between the metric system (17.1) and the English system, there is a 0.1 discrepancy (17.0). This discrepancy results from rounding from two to one decimal place.
How is BMI converted to kilograms?
BMI is calculated as follows: kg = weight in kilograms/m2, where m2 equals height in meters squared. Overweight is defined as a BMI of 25.0 or higher, whereas the healthy range is 18.5 to 24.9.
How is the BMI determined for men?
- Use the following formula to determine BMI in metric units: kg/m2 = BMI
- In order to determine an adult’s BMI: their height in meters squared by their weight in kilograms (kg) (m2)
What is the simplest method to determine your BMI?
To determine your BMI, multiply the results by a conversion factor of 703 and then divide your weight in pounds by your height in squared inches. The formula would be as follows for a person who is 150 pounds and 5 feet 5 inches tall (65 inches): x 703 = 24.96
How is BMI determined using height and feet?
Your BMI will be determined, for instance, as follows if your weight is 60 kilograms and your height is 5 feet 3 inches:
60 / 2.61 (1.6 * 1.6) (5 feet 3 inches is approximately 1.6 meters)
This results in a BMI of 22.9.
How is BMI determined in kg and CM?
BMI is calculated using the metric system, which divides weight in kilograms by height in meters squared. Since height is typically measured in millimeters, a different calculating procedure can be employed. It involves dividing the weight in kilograms by the square of the height in centimeters, then multiplying the result by 10,000.
When utilizing a portable calculator:
- Divide weight (kg) by height (cm) squared, multiply by 10,000, then round to the nearest tenth of a decimal place if your calculator includes a square function.
- If your calculator does not include a square function, multiply by 10,000 and round to the nearest tenth of a decimal place after dividing weight by height twice as indicated in the calculation procedure above.
Sam’s weight and height are both known to be 16.9 kg and 105.4 cm respectively. How tall is Sam?
Describe BMI using an example.
The body mass index (BMI) is what. Using your height and weight, the body mass index (BMI) calculates whether your weight is healthy. The BMI formula divides an adult’s kilogram weight by their squared height. For instance, a BMI of 25 equates to 25 kg/m2.
Is BMI limited to weight and height?
A person can evaluate whether or not their weight is healthy for them by using the body mass index (BMI). Height and weight are both factors in BMI. Being overweight or underweight might raise a person’s risk of health issues, both now and in the future.
The BMI: Is it reliable?
By dividing a person’s weight by the square of their height, the Body Mass Index (BMI) calculation generates a number that corresponds to one of the following bodyweight categories:
A high BMI can be used to screen for specific weight levels that could result in health issues in addition to classifying a person into one of these categories. A high BMI can also be a marker of a high body fat percentage. Although it is frequently used as one, it is not a reliable indicator of body fatness or of a person’s general health.
The majority of us who are interested in fitness have probably heard that BMI is far from an accurate measurement. The BMI assessment may frequently, and frequently when it really matters, overestimate or even underestimate a person’s body fat. It truly does when it does, too.
What alternative to BMI is there?
- ratio of waist to height (WHtR) Waist-to-height ratio, the BMI’s cousin, relates waist circumference to height rather than total weight to height squared.
- Measurements.
- heart rate at rest (RHR)
- Calipers that fold up
How is true weight determined?
- A is your highest weight before pregnancy.
- Your all-time lowest weight is equal to B.
- Figure out (a + b) / 2 = C.
- D is the weight you have maintained over the course of your life.
- The weight that you aspire to be: E.
- Figure out D + (E x 2) Equals F.
- You are G meters tall.
- Calculate GxGx42 to get H.
What is a healthy BMI for women?
ranges for women’s BMI For women, a healthy BMI ranges from 18.5 to 24.9. To see your weight category, see your BMI in the chart below. You can use your pre-pregnancy BMI to determine your recommended weight gain if you are pregnant or intend to become pregnant.
What BMI is ideal for an elderly woman?
Obesity strains the heart and can result in major health issues. These consist of:
There are numerous websites with calculators where you may enter your weight and height to get your BMI.
You can also figure it out on your own:
- Add 703 to your weight in pounds.
- Subtract that result from your height in inches.
- Once more, multiply that result by your height in inches.
A lady with a BMI of 41.0, for instance, would be 270 pounds (122 kilograms) in weight and 68 inches (172 cm) tall.
Use the following table to determine your BMI category and whether you should be concerned about your weight.
The greatest technique to determine if you should lose weight is not usually to look at your BMI. Your BMI may not be an accurate indicator of how much body fat you have if you have more or less muscle than is typical:
- muscle builders People who are exceptionally muscular may have a high BMI because muscle weighs more than fat.
- the elderly. In elderly persons, a BMI between 25 and 27 is frequently preferable to one under 25. For instance, if you are older than 65, a slightly higher BMI may help shield you against bone weakening (osteoporosis).
- Children. Despite the fact that many youngsters are obese, DO NOT use this BMI calculator to assess a child. Find out from your child’s doctor what weight is appropriate for their age.
A few techniques are used by providers to determine whether you are overweight. Your waist circumference and waist-to-hip ratio may also be taken into account by your healthcare professional.
Although your BMI alone cannot forecast your health risk, the majority of medical professionals agree that obesity (a BMI above 30) is unhealthy. Exercise can lower your risk of acquiring diabetes and heart disease regardless of BMI. Always consult your doctor before beginning an exercise program.
Why does my BMI indicate that I’m overweight despite not being?
BMI does not take into consideration body composition, hence it does not distinguish between muscle mass and fat mass.
Bodybuilders and other professional athletes, such as football players, are frequently classified as obese or overweight based only on their BMI since muscles are denser and heavier than fat.
Most likely, a person who has a high BMI because of muscle mass need not be concerned about the health issues related to obesity and being overweight.
What should the optimal body weight be?
We read Hedenstierna and Edmark’s commentary on protected ventilation in the December issue of Anesthesiology with great interest.
1 The majority of the suggestions made have our support. However, as thoracic anesthesiologists, we firmly feel that modest tidal volume based on optimal body weight is crucial during one-lung breathing. 2,3
The gender-specific Acute Respiratory Distress Syndrome Network (ARDSnet) formulas are still frequently suggested by authors when determining optimal body weight.
4 For men, the ideal body weight is 50 + (0.91 x [height in cm – 152.4]), while for women, 45.5 + (0.91 x [height in centimeters – 152.4]). An easy substitute would be to determine optimum body weight as the amount of weight that corresponds to a body mass index of 22 kg/m2. Then, to determine the ideal body weight, multiply 22 by [[the actual patient’s height in meters]2] or use the body mass index charts found on our anesthesia cart. 5 After weighing the ideal body weights corresponding to body mass indices between 20 and 25 with the ideal body weight determined using ADRSnet methods, we determined that 22 kg/m2 was the perfect BMI. For instance, a 1.75-m man’s optimum body weight would be 67 kg (22 x [1.752]) as opposed to 71 kg if using ARDSnet, while a 1.60-m woman’s ideal body weight would be 56 kg (22 x [1.602]) as opposed to 52 kg.
The approach we provide is straightforward and simple to remember. Men and women must perform the same calculation, which just requires basic arithmetic.
