How to Convert Radian/second² to RPM/second

Converting Radian/second² (rad/s²) to RPM/second (rev/(min·s)) is a core calculation in Angular Acceleration, which measures the rate of change of rotational velocity over time about a rotation axis. Because Radian/second² represents a larger magnitude than RPM/second, converting from rad/s² to rev/(min·s) expands the numerical figure. Exactly 1 Radian/second² encompasses 9.549297 RPM/second. To convert any quantity, multiply the value in Radian/second² 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 squared (rad/s²)) 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/s² = 1 radian per second squared (rad/s²)

2. Target SI Bridge (k_target):1 rev/(min·s) = 0.10472 radian per second squared (rad/s²)

Step-by-step substitution for Radian/second² → RPM/second:V(rev/(min·s)) = V(rad/s²) × ( 1 / 0.10472 ) = V(rad/s²) × 9.549297
