Here, we organize measured values into coefficients that are easy to use for calculations and comparisons. Unless otherwise specified, numerical units are normalized values based on Stormworks Torque (ST) and dRPS / tick.
Legend
| Symbol | Meaning |
|---|
| ST | Value from Torque Meter. Measured value including rotational inertia |
| RPS | Revolutions per second |
| dRPS | Difference in RPS per tick |
| Resistance Coefficient | dRPS × ST / RPS. A negative value dampens rotation |
| Power Coefficient | dRPS × ST / Throttle. Power generated per unit of throttle |

If the resistance coefficient is c and RPS is x, the normalized power due to resistance is approximately c × x. When connecting multiple components, add each component's coefficient to the base value.
