Body Mass Index (BMI) & Target Weight Calculator
Quetelet's Body Mass Index (BMI) normalizes human body mass m (in kilograms) by the square of standing height h (in meters): BMI = m / h².
Mass-to-height-squared ratio in kg/m²
Body weight in kilograms (switch inline unit to Pounds lb)
Height in meters (switch inline unit to cm, ft, or in)
Step-by-Step Calculation

Frequently Asked Questions
How do I find my exact weight for a target BMI of 22.0?+
Click SOLVE FOR on m (Body Mass), enter your height h (in m, cm, or ft), and set BMI = 22.0.
Can I enter weight in pounds (lb) and height in centimeters (cm) or inches (in)?+
Yes. Use the inline unit selectors on m (kg / lb) and h (m / cm / ft / in) for automatic conversion.
Why can strength athletes have an elevated BMI at low body fat?+
BMI measures total mass per unit height squared and cannot differentiate dense lean skeletal muscle from fat mass.
