Health and fitness calculators based on medical standards
Monitor your health metrics with calculators built on established medical standards. Our BMI calculator uses WHO classification guidelines, the calorie calculator implements the Mifflin-St Jeor equation recognized as one of the most accurate basal metabolic rate formulas, and the body fat calculator uses the US Navy circumference method validated in peer-reviewed research. Each tool includes context about what the numbers mean, their limitations, and when to consult a healthcare professional. We believe health data should be accessible and understandable.
Why This Matters
Understanding your health metrics is the first step toward making informed wellness decisions. However, health calculators are only useful when they are based on validated methods and clearly explain their limitations. We prioritize scientific accuracy and transparency β every formula is cited, every limitation is disclosed, and every tool includes a disclaimer encouraging professional medical consultation for personalized advice.
