Explain it like I'm 12
The healthy weight calculator reverses the adult BMI formula for BMI 18.5 to 24.9, then shows a Devine ideal-weight estimate beside that range for context.
Healthy range low = 18.5 × height(m)^2. Healthy range high = 24.9 × height(m)^2. 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
At 178 cm, height is 1.78 m. The common adult BMI 18.5-24.9 range is about 58.6-78.9 kg. The male Devine comparison is about 73.2 kg.

Methodology & Accuracy
How this calculator is checked
CalculationTime pages are built around visible arithmetic: the formula, assumptions, worked example and practical limitations are shown so the result can be checked rather than simply trusted.
Formula used
Healthy range low = 18.5 × height(m)^2. Healthy range high = 24.9 × height(m)^2. 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.
Standard or basis
Adult health education estimate using metric height.
Where a calculator follows a named legal, trade or industry standard, that standard is cited visibly. Otherwise the page uses transparent general arithmetic and states its limits.
