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 (rad)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)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 (ksource):1 Turn = 360 radian (rad)
2. Target SI Bridge (ktarget):1 " = 0.000277778 radian (rad)
Step-by-step substitution for Turn → Second:V(") = V(Turn) × ( 360 / 0.000277778 ) = V(Turn) × 1296000
Mathematical FormulaValue in Second = Value in Turn × 1296000Direct computational formula applied for standard conversion.
Worked Example

To convert 120 Turn (Turn) to Second ("): multiply 120 by 1296000 to get 1.5552 × 10⁸ ". At an industrial engineering scale, 5000 Turn converts to 6.48 × 10⁹ ".

Inverse check: 1 " = 7.716049 × 10⁻⁷ Turn.
