BMI
HealthEstimate body mass index from height and weight, with adult screening category context.
- What is my estimated BMI?
- Which adult BMI category does it fall into?
Estimate energy expenditure from activity, body weight, and duration using MET values.
Change the inputs that matter to your decision. Optional assumptions stay collapsed until you need them.
Select a standard activity estimate or enter a custom MET value when you have one.
30 minutes at 3.5 MET for 75.0 kg.
Energy expenditure varies with pace, terrain, fitness, technique, and individual physiology.
| Walking at 3.5 MET | 30 min |
|---|---|
| Running at 9.8 MET | 11 min |
Preset MET values are population-level activity estimates; they are not a measurement of calories burned by your body.
Practical notes about the inputs, assumptions, and result.
A MET is a standardized multiple of resting energy expenditure used to describe activity intensity.
No. MET calculations are estimates and can differ from wearable-device readings and individual physiology.
The calculation multiplies the activity's MET value by body weight in kilograms and duration, so the same activity and time produces a different estimate at a different weight.
Use a custom value only when you have a suitable activity reference for the specific pace or task. A custom MET still gives a planning estimate, not a personal measurement.
