Mathematical Formulas & Calculation Methods

BMI Formula (Metric & Imperial)

To calculate bmi online, divide weight in kg by height in meters squared (or weight in lbs × 703 divided by height in inches squared).

Metric: BMI = Weight(kg) ÷ (Height(m))² Imperial: BMI = (Weight(lbs) ÷ (Height(in))²) × 703

Worked Step-by-Step Examples

Example 1: Metric BMI Calculation (70 kg, 175 cm)

"Calculate BMI for an adult weighing 70 kg at a height of 175 cm (1.75 m)."

Steps:

Height squared: 1.75 × 1.75 = 3.0625 m²
BMI = 70 ÷ 3.0625 = 22.86 kg/m²

Result: BMI is 22.9 (Normal Weight / Healthy Range).
