How to Convert Radian/minute to Revolution/day

Converting Radian/minute (rad/min) to Revolution/day (rev/d) is a core calculation in Angular Velocity, which measures the rotational speed and rate of angular displacement per unit of time. Because Radian/minute represents a larger magnitude than Revolution/day, converting from rad/min to rev/d expands the numerical figure. Exactly 1 Radian/minute encompasses 229.183118 Revolution/day. To convert any quantity, multiply the value in Radian/minute 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 rad/min = 0.0166667 radian per second (rad/s)

2. Target SI Bridge (k_target):1 rev/d = 7.272205 × 10⁻⁵ radian per second (rad/s)

Step-by-step substitution for Radian/minute → Revolution/day:V(rev/d) = V(rad/min) × ( 0.0166667 / 7.272205 × 10⁻⁵ ) = V(rad/min) × 229.183118

Mathematical FormulaValue in Revolution/day = Value in Radian/minute × 229.18311805Direct computational formula applied for standard conversion.

Worked Example

To convert 50 Radian/minute (rad/min) to Revolution/day (rev/d): multiply 50 by 229.183118 to get 11459.155903 rev/d. At an industrial engineering scale, 1000 rad/min converts to 229183.118052 rev/d.

Inverse check: 1 rev/d = 0.00436332 rad/min.
