Ideal Body Weight Calculator
Ideal body weight formulas estimate a healthy weight based on height and gender. Multiple formulas exist because there is no single agreed-upon standard. Results are shown in pounds; multiply by 0.4536 to convert to kilograms.
Conversion Formula
All formulas use a base weight for 5 feet (152.4 cm) and add a per-inch increment for additional height.
Step-by-Step Examples
Male, 5'10" (178 cm) = Devine: 160.6 lbs (72.8 kg)
110 + 5.06 × 10 = 160.6 lbs
Frequently Asked Questions
What is ideal body weight?
Ideal body weight (IBW) is an estimated weight associated with the lowest risk of health problems for a given height. For example, a 5'10" (178 cm) male has a Devine IBW of about 160.6 lbs (72.8 kg).
Which formula is most accurate?
The Devine formula is most commonly used in clinical settings. All formulas are estimates and do not account for body composition.
Should I use IBW as a weight goal?
IBW is a reference point, not a strict goal. Consult a healthcare provider for personalized recommendations.
How do I convert the results to metric?
Multiply pounds by 0.4536 to get kilograms. For example, a Devine result of 160.6 lbs is about 72.8 kg. The formulas are based on height in inches, but 1 inch = 2.54 cm, so 5'10" = 70 in = 177.8 cm.
