How to Convert Radian/second to Degree/hour

Converting Radian/second (rad/s) to Degree/hour (°/h) is a core calculation in Angular Velocity, which measures the rotational speed and rate of angular displacement per unit of time. Because Radian/second represents a larger magnitude than Degree/hour, converting from rad/s to °/h expands the numerical figure. Exactly 1 Radian/second encompasses 206264.806247 Degree/hour. To convert any quantity, multiply the value in Radian/second by 206264.806247.

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/s = 1 radian per second (rad/s)

2. Target SI Bridge (k_target):1 °/h = 4.848137 × 10⁻⁶ radian per second (rad/s)

Step-by-step substitution for Radian/second → Degree/hour:V(°/h) = V(rad/s) × ( 1 / 4.848137 × 10⁻⁶ ) = V(rad/s) × 206264.806247

Mathematical FormulaValue in Degree/hour = Value in Radian/second × 206264.8062471Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 15 rad/s, applying the conversion factor yields exactly 3093972.093706 °/h. At larger operational scale, 240 Radian/second corresponds to 4.950355 × 10⁷ °/h.

Inverse check: 1 °/h = 4.848137 × 10⁻⁶ rad/s.
