# Calories burned estimator

Canonical page: https://nepocore.com/tools/calories-burned/

Estimate activity energy from duration, body weight and a chosen MET value. This browser tool shows the inputs, assumptions and resulting output so you can use it for a specific everyday task.

## How to use it

1. Enter your own values or choose a supported file.
2. Adjust the options and run the tool.
3. Review the result, then copy, export or save it when available.

## Example

Estimate gross energy for a 65 kg adult doing 30 minutes of a 4-MET activity.

## Limits and checks

MET values are population averages. Gross energy includes resting energy and does not precisely measure your individual workout.

## Access and processing
