How to Convert Revolution/minute to Degree/day

Converting Revolution/minute (rpm) to Degree/day (°/d) is a core calculation in Angular Velocity, which measures the rotational speed and rate of angular displacement per unit of time. Because Revolution/minute represents a larger magnitude than Degree/day, converting from rpm to °/d expands the numerical figure. Exactly 1 Revolution/minute encompasses 518400 Degree/day. To convert any quantity, multiply the value in Revolution/minute by 518400.

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 rpm = 0.10472 radian per second (rad/s)

2. Target SI Bridge (k_target):1 °/d = 2.020057 × 10⁻⁷ radian per second (rad/s)

Step-by-step substitution for Revolution/minute → Degree/day:V(°/d) = V(rpm) × ( 0.10472 / 2.020057 × 10⁻⁷ ) = V(rpm) × 518400

Mathematical FormulaValue in Degree/day = Value in Revolution/minute × 518400Direct computational formula applied for standard conversion.

Worked Example

To convert 24 Revolution/minute (rpm) to Degree/day (°/d): multiply 24 by 518400 to get 1.24416 × 10⁷ °/d. At an industrial engineering scale, 1000 rpm converts to 5.184 × 10⁸ °/d.

Inverse check: 1 °/d = 1.929012 × 10⁻⁶ rpm.
