Body Mass Index is a simple calculation using a person's height and weight. The formula is BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in metres squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9. BMI applies to most adults 18-65 years.
How do you calculate BMI in pounds?
Then, calculate BMI by dividing weight in pounds (lb) by height in inches (in) squared and multiplying by a conversion factor of 703. When using a handheld calculator, if your calculator has a square function, divide weight (lb) by height (in) squared, multiply by 703, and round to one decimal place.
How do you calculate BMI from weight lbs and height inches?
- Formula: weight (lb) / [height (in)]2 x 703. Calculate BMI by dividing weight in pounds (lbs) by height in inches (in) squared and multiplying by a conversion factor of 703.
- Example: Weight = 150 lbs, Height = 5'5” (65″)
- Calculation: 150 ÷ (65 x 65) x 703 = 24.96.
