How to Convert Revolution/hour to Radian/minute

Converting Revolution/hour (rev/h) to Radian/minute (rad/min) is a core calculation in Angular Velocity, which measures the rotational speed and rate of angular displacement per unit of time. Because Radian/minute is a broader physical scale than Revolution/hour, converting from rev/h to rad/min condenses the numerical figure. It takes 9.549297 Revolution/hour to equal a single Radian/minute (1 rev/h = 0.10472 rad/min). To convert any quantity, multiply by 0.10472 (or divide by 9.549297).

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (radian per second (rad/s)) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 rev/h = 0.00174533 radian per second (rad/s)

2. Target SI Bridge (k_target):1 rad/min = 0.0166667 radian per second (rad/s)

Step-by-step substitution for Revolution/hour → Radian/minute:V(rad/min) = V(rev/h) × ( 0.00174533 / 0.0166667 ) = V(rev/h) × 0.10472

Mathematical FormulaValue in Radian/minute = Value in Revolution/hour × 0.10471976Direct computational formula applied for standard conversion.

Worked Example

To convert 50 Revolution/hour (rev/h) to Radian/minute (rad/min): multiply 50 by 0.10472 to get 5.235988 rad/min. At an industrial engineering scale, 100 rev/h converts to 10.471976 rad/min.

Inverse check: 1 rad/min = 9.549297 rev/h.
