Health
Calories Burned Calculator
Estimate calories burned during exercise from body weight, activity intensity (METs), and duration. Use it to track exercise contribution to your daily calorie balance and to compare relative energy cost of different activities.
Fitness
BMI Calculator
Calculate Body Mass Index (BMI) — body weight in kg divided by height in metres squared — to screen for under/overweight categories. The most widely used population-level fitness and health risk metric, with known limitations for athletes and unusual body compositions.
