FAQ
How is ideal weight calculated?+
This calculator uses the Devine formula: 50 kg for men or 45.5 kg for women, plus 2.3 kg for every inch of height over 5 feet. The result is shown in both kilograms and pounds.
Is the Devine formula accurate?+
It was originally developed in 1974 for calculating medication doses, not as a health target, so treat it as a rough guideline. It ignores frame size, muscle mass and body composition, and a healthy weight is really a range, not a single number.
