Decision view
Gross activity energy versus the resting comparison
Gross activity energy versus the resting comparisonResting energy is separated from gross session energy; the signed difference can be negative when activity MET is below the entered resting MET.
Gross and above-rest session energy by MET intensityActivity MET changes while duration, body weight, and resting MET remain fixed; gross and signed relative-to-rest session energy stay separate.
Exact scenario comparisonActivity MET value changes while all other entered assumptions remain constant.

How to use MET Activity Calorie Calculator
- Choose a MET value that matches the activity and actual intensity as closely as possible.
- Use a representative body weight and the minutes spent at that intensity.
- Decide whether gross energy or above-rest energy answers the planning question.
- Treat weekly totals as repeated estimates only when session duration and intensity are comparable.
Calculator guide
Understanding MET Activity Calorie Calculator
A MET calculation converts a catalogued activity intensity into an energy estimate for a specific body weight and duration. This page keeps gross activity energy separate from energy that would have been used at rest during the same minutes.
Calculation method
How the calculation works
Apply the standard MET oxygen-cost conversion to body weight and minutes, and report gross energy separately from the signed energy difference relative to the entered resting comparison. Gross kilocalories per minute equal MET × 3.5 × body weight in kilograms ÷ 200. Multiplying by duration gives gross session energy. The same calculation using the entered resting MET is subtracted to show energy above rest; weekly values multiply each session estimate by sessions per week.
Interpretation choice
When to use gross versus above-rest energy
Choose the output that matches the comparison instead of treating both as interchangeable.
Worked situations
Practical examples
- A 6-MET session includes resting energy as part of its gross total.
- Two people doing the same activity can receive different estimates because body weight differs.
- Increasing weekly frequency changes the weekly total but not the per-session estimate.
Better inputs
Useful tips
- Record the source and activity description attached to the MET value.
- Split a variable-intensity workout into segments instead of assigning one MET to the whole session.
- Compare estimates from the same convention—gross with gross or net with net.
Before relying on the result
Limitations and common mistakes
- MET tables contain population averages rather than personal metabolic measurements.
- Fitness, movement economy, body composition, temperature, altitude, and technique can change actual expenditure.
- The formula does not establish a safe exercise intensity or a dietary prescription.
Reference
Key terms
- MET
- A multiple of an assumed resting metabolic rate.
- Gross energy
- Estimated total energy used during the entered activity time, including rest.
- Above-rest energy
- Gross activity energy minus the entered resting comparison.
- Session estimate
- Calculated energy for one entered duration.

Frequently asked questions
Is one MET exactly one resting metabolic rate for everyone?
No. The conventional value is a standardized reference and individual resting metabolism varies.
Why is the above-rest result smaller?
It removes the modeled energy that would have been used at the entered resting MET.
Can this calculate calories from a fitness tracker?
It provides an independent formula estimate; tracker algorithms and sensor inputs may use different methods.
Should exercise calories be eaten back?
That is an individualized nutrition decision and cannot be determined by this arithmetic alone.
