Health & Fitness Calculators

Check BMI, daily calorie needs, ideal weight and fitness targets with simple inputs. These calculators give a quick, honest starting point for health goals — they never store or share your numbers. The first live tool is the BMI Calculator: enter weight and height and it shows your body mass index from the standard formula, the WHO category, and the healthy weight range for your height, with metric and imperial units. Later batches add calorie and macro calculators, ideal-weight ranges, body-fat estimators, water-intake guides and workout timers. Everything runs in your browser, so your weight and measurements stay on your device. These tools are for general information and planning, not medical advice — if a result worries you, talk to a doctor, and each calculator says that on its page. The results are presented with context — what the number means, what the healthy range is, and what to do next — instead of a bare figure. No account is needed, nothing is uploaded, and the tools are free for everyday use.
