How to Convert Kilomol/hour to Mol/second

Converting Kilomol/hour (kmol/h) to Mol/second (mol/s) is a core calculation in Molar Flow Rate, which measures the chemical amount of substance (in moles) flowing through a boundary per unit of time. Because Mol/second is a broader physical scale than Kilomol/hour, converting from kmol/h to mol/s condenses the numerical figure. It takes 3.6 Kilomol/hour to equal a single Mol/second (1 kmol/h = 0.277778 mol/s). To convert any quantity, multiply by 0.277778 (or divide by 3.6).

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 (mole per second (mol/s)) 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 kmol/h = 0.277778 mole per second (mol/s)
2. Target SI Bridge (ktarget):1 mol/s = 1 mole per second (mol/s)
Step-by-step substitution for Kilomol/hour → Mol/second:V(mol/s) = V(kmol/h) × ( 0.277778 / 1 ) = V(kmol/h) × 0.277778
Mathematical FormulaValue in Mol/second = Value in Kilomol/hour × 0.27777778Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 75 kmol/h, applying the conversion factor yields exactly 20.833333 mol/s. At larger operational scale, 480 Kilomol/hour corresponds to 133.333333 mol/s.

Inverse check: 1 mol/s = 3.6 kmol/h.
