Formula and methodology
Formula: height=floors×steps per floor×riser; metabolic kcal=(mass×9.80665×height)/(efficiency/100×4184).
This is a physics-based vertical-work scenario. It reports height and mechanical work before applying the user-entered efficiency so the main assumption is visible rather than hidden in a calorie constant.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Body mass — kg; minimum 20; maximum 350
- Floors climbed — minimum 1.0E-6; maximum 10000
- Steps per floor — minimum 1; maximum 1000
- Riser height — cm; minimum 0.1; maximum 100
- Mechanical efficiency — %; minimum 5; maximum 50
Worked example
| Input | Value |
|---|---|
| Body mass | 70 |
| Floors climbed | 10 |
| Steps per floor | 16 |
| Riser height | 18 |
| Mechanical efficiency | 25 |
The climb raises the body 28.8 m and estimates about 18.90 kcal of metabolic energy.
Assumptions and limits
- The body is raised by the full entered riser height on every step.
- Efficiency is a planning assumption and does not include descent or horizontal movement.
- The result is educational and not a personal nutrition or exercise prescription.
