Explain it like I'm 12
The ideal body weight calculator converts height to inches over five feet, applies adult IBW formulas, and cross-checks the result against the BMI 18.5-24.9 range.
Devine IBW kg = 50 + 2.3 × inches over 5 ft for male formula, or 45.5 + 2.3 × inches over 5 ft for female formula.
Worked example
A 178 cm adult is about 10.1 inches over 5 ft. Male Devine IBW is 50 + 2.3×10.1 = about 73.2 kg.
