Formula and calculation method

Gross energy (kcal) = MET × 3.5 × body weight in kg / 200 × minutes. Net energy subtracts 1 MET.

MET is user-entered. Gross energy includes resting expenditure; fitness devices may report net energy instead.

How to use calories burned calculator

  1. Set Measurement system by choosing the option that matches your calculation.
  2. Set Weight (kg or lb). The example below uses 70.
  3. Set Activity MET value. The example below uses 5.

Factors affecting your result

MET is user-entered. Gross energy includes resting expenditure; fitness devices may report net energy instead.

Changing measurement system changes the scenario being evaluated. Adjust one input at a time when comparing results, keep a copy of the assumptions, and compare values using the same unit and period. A precise arithmetic result does not make an uncertain assumption precise.

Frequently asked questions

How does the calories burned calculator work?

Gross energy (kcal) = MET × 3.5 × body weight in kg / 200 × minutes. Net energy subtracts 1 MET.

What inputs does Calories Burned Calculator need?

Enter measurement system, weight (kg or lb), activity met value, activity minutes. Choose values that correspond to the same situation and measurement convention.

How should I interpret the calories burned calculator result?

MET is user-entered. Gross energy includes resting expenditure; fitness devices may report net energy instead.

Are my calories burned calculator inputs uploaded?

No. The calculation runs in this browser. Favorites, recent tool names, theme and formatting preferences may be saved locally, but calculation inputs are not sent to a calculation server or stored by this website. Shared links do not include entered values.
