Convert measured peak power and body weight into watts per kilogram, then test a weight-change scenario against a user-selected target. The calculator describes a ratio, not pitching velocity or medical readiness.
Current power-to-weight ratio is calculated directly from the entered scenario. Read it together with the supporting figures so the assumptions remain visible.
Planning estimate only. Verify important athletic, financial, or infrastructure decisions with qualified staff and real-world measurements.
At 1,600 watts and 190 lb (86.2 kg), the ratio is 18.57 W/kg. With no weight change, the scenario ratio is unchanged.
It uses the values shown in the calculator panel and applies only the formula documented on this page.
Zero is accepted where it represents a valid absence of cost, volume, allocation, or activity; fields that form a divisor must remain above zero.
No. The result is a scenario estimate based on your inputs, not a guarantee of athletic, financial, or technical performance.
Change one assumption at a time, calculate again, and compare the main result with the secondary metrics.
Real outcomes can vary because of measurement error, changing participation, individual condition, infrastructure overhead, or other factors outside this simplified model.
| Input | Unit | Role |
|---|---|---|
| Peak power | W | Measured peak mechanical power. |
| Body weight | lb | Current body weight. |
| Target ratio | W/kg | Optional performance planning target. |
| Planned weight change | lb | Positive for gain, negative for loss. |
