A familiar situation
Compare approximate energy use across activities using duration, body weight, and an average MET value.
How to use this calculator
- Enter weight, activity (met), duration.
- Select Calculate to see the answer and its breakdown.
- Keep a scenario, change an input and compare the results.
Use consistent units and check the assumptions below before applying the result.
How calories burned is calculated
Approximate gross kcal = MET × 3.5 × weight(kg) ÷ 200 × minutes. MET values are standardized activity intensities; actual energy use varies with pace and physiology. For a 70 kg person walking at 3.5 MET for 30 minutes, estimated gross expenditure is about 129 kcal.
Gross kcal≈MET×3.5×weight(kg)/200×minutes.For a 70 kg person walking at 3.5 MET for 30 minutes, estimated gross expenditure is about 129 kcal.
Assumptions & useful context
MET-based average; actual energy use varies and this includes resting energy during the activity.
Health calculations are estimates for education. They cannot diagnose a condition or replace a clinician’s assessment. Individual needs vary, especially during pregnancy, illness and growth.
Frequently asked questions
Are these calories exact?
No. A MET estimate cannot capture individual movement economy or actual intensity precisely.
Does gross calorie burn subtract resting energy?
No. It includes the energy that would also be spent at rest during that time.
