3D Calories Burned Calculator

The number of calories burned during daily activities or exercise varies due to multiple factors, making it an estimate rather than an exact measurement. This calculator, like others, uses standardized data based on an “average” person. For details on calorie intake for weight management, refer to the Calorie Calculator.

Calories burned depend on body mass, exercise duration, and intensity. A heavier person burns more calories at rest and during activity. Longer and more intense exercises result in greater calorie expenditure. Intensity can be measured by heart rate or oxygen consumption (MET values), with higher MET indicating more energy used.

Additional factors like age, body composition, temperature, fitness level, diet, and sleep also influence calorie burn. Older individuals and those with lower muscle mass tend to burn fewer calories. Warmer environments, higher metabolism, and better fitness efficiency impact results as well.

This calculator estimates calories burned using:
Calories = (Time × MET × Body Weight) ÷ 200
MET values, derived from studies, provide an estimate but may not be entirely accurate due to variations in individual metabolic rates and activity consistency. The most precise measurement requires lab testing, but MET remains a useful intensity index.
