Calculators for body and nutrition: Body Mass Index with WHO categories and your healthy weight range, plus daily calorie needs — baseline burn, maintenance and a target adjusted for your activity level. Both calculators work with metric and imperial units, need no sign-up and run entirely in your browser: enter two or four numbers and get an immediate, clearly interpreted result.

Useful if you watch your weight, plan your nutrition or start training: a quick check with clear reference points. Remember that both metrics are screening estimates — use them to track direction over time rather than as medical verdicts.
