About the bmi calculator
Calculate body mass index from height and weight using metric or imperial measurements. This tool is designed to provide a quick estimate with clear, easy-to-understand results. It runs in your browser and does not require you to create an account.
How the calculation works
BMI = weight in kilograms ÷ (height in metres × height in metres). BMI is a screening measure, not a diagnosis.
Example
A weight of 70 kg and height of 1.70 m gives a BMI of about 24.2.
When should you use it?
Use this calculator for planning, checking estimates, comparing options, and understanding the effect of different input values. Results depend on the information you enter and may not include fees, exceptions, or local rules that are not explicitly represented.
