How to Convert Revolution/day to Radian/minute

Converting Revolution/day (rev/d) 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/day, converting from rev/d to rad/min condenses the numerical figure. It takes 229.183118 Revolution/day to equal a single Radian/minute (1 rev/d = 0.00436332 rad/min). To convert any quantity, multiply by 0.00436332 (or divide by 229.183118).

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/d = 7.272205 × 10⁻⁵ 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/day → Radian/minute:V(rad/min) = V(rev/d) × ( 7.272205 × 10⁻⁵ / 0.0166667 ) = V(rev/d) × 0.00436332

Mathematical FormulaValue in Radian/minute = Value in Revolution/day × 0.0043633231Direct computational formula applied for standard conversion.

Worked Example

Evaluating an input of 12 Revolution/day (rev/d) produces 0.0523599 Radian/minute (rad/min). In heavy-duty utility and industrial workloads, 240 rev/d equals 1.047198 rad/min.

Inverse check: 1 rad/min = 229.183118 rev/d.
