# How to calculate bmi

Use a scale to measure your weight in kilograms (kg) or pounds (lbs). Ensure the accuracy of the measurement.

Use a tape measure or height measuring tool to measure your height in meters (m) or feet (ft). Ensure the accuracy of the measurement.

3. Convert height to meters if necessary:

If you measured your height in feet and inches, convert it to meters. One foot is equivalent to 0.3048 meters, and one inch is equivalent to 0.0254 meters. For example, if you are 5 feet 8 inches tall, your height in meters would be 1.73 meters (5 ft x 0.3048 + 8 in x 0.0254 = 1.52 + 0.20 = 1.73 meters).

Use the following formula to calculate your BMI:

BMI = weight (kg) / (height (m) x height (m))

Alternatively, if you prefer to use pounds and inches, you can use the following formula:

BMI = (weight (lbs) / (height (in) x height (in))) x 703

For example, if you weigh 70 kg and your height is 1.73 meters, your BMI would be calculated as follows:

BMI = 70 kg / (1.73 m x 1.73 m) = 23.4

If you weigh 150 lbs and your height is 5 feet 8 inches (68 inches), your BMI would be calculated as follows:

BMI = (150 lbs / (68 in x 68 in)) x 703 = 22.8
