Measure your height (in meters) and weight (in kilograms)
Use the formula: BMI = weight (kg) / (height (m))^2
Convert units if needed:
If height is in centimeters: height (m) = height (cm) / 100
If weight is in pounds: weight (kg) = weight (lb) / 2.20462
If height is in inches: height (m) = height (in) × 0.0254
Calculate BMI using the converted values
(Optional) Use the calculator formula with pounds/inches:
BMI = (weight (lb) / height (in)^2) × 703
Record the final BMI value
