How to Convert Revolution/day to Revolution/second

Converting Revolution/day (rev/d) to Revolution/second (rev/s) is a core calculation in Angular Velocity, which measures the rotational speed and rate of angular displacement per unit of time. Because Revolution/second is a broader physical scale than Revolution/day, converting from rev/d to rev/s condenses the numerical figure. It takes 86400 Revolution/day to equal a single Revolution/second (1 rev/d = 1.157407 × 10⁻⁵ rev/s). To convert any quantity, multiply by 1.157407 × 10⁻⁵ (or divide by 86400).

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 rev/s = 6.283185 radian per second (rad/s)

Step-by-step substitution for Revolution/day → Revolution/second:V(rev/s) = V(rev/d) × ( 7.272205 × 10⁻⁵ / 6.283185 ) = V(rev/d) × 1.157407 × 10⁻⁵

Worked Example

Converting 250 rev/d yields an exact output of 0.00289352 rev/s in Revolution/second. Under higher industrial throughput, 10000 rev/d translates to 0.115741 rev/s.

Inverse check: 1 rev/s = 86400 rev/d.
