What This BMI Calculator Is For

Estimate Body Mass Index

The BMI calculator estimates Body Mass Index from height and weight and shows a category based on common adult BMI ranges.

It supports metric and imperial input so you can compare kg/cm and lb/ft/in values without manual conversion.

Use BMI as a General Screening Tool

BMI can be useful for population-level screening and quick personal reference, but it does not measure body fat directly and cannot account for muscle mass, pregnancy, age-specific needs, or medical history.

For health decisions, discuss the result with a qualified medical professional.

Use accurate height and weight measurements.
Check the healthy weight range as a rough reference, not a diagnosis.
Do not use adult BMI categories for children without age-specific guidance.
Seek professional advice for medical, nutrition, or treatment decisions.

FAQ

Which BMI categories are used?

The calculator uses standard WHO adult BMI categories.

Does this replace medical advice?

No. It is an informational tool and not a clinical diagnosis.

Can athletes get misleading BMI results?

Yes. BMI uses only height and weight, so people with high muscle mass can receive a high BMI even when body fat is not high.

Can I use imperial units?

Yes. The calculator supports both metric and imperial inputs and converts the values for the BMI formula.
