How to Convert Kilomole/hour to Pound mole/second

Converting Kilomole/hour (kmol/h) to Pound mole/second (lb-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. This calculation navigates the boundary between the International Metric System (SI) and British Imperial / US Customary engineering standards. In contemporary metrology, Imperial units are defined in terms of exact SI standards via international agreements—notably NIST SP 811 and the 1959 International Yard and Pound Agreement. Exactly 1 Kilomole/hour equals 0.000612395 Pound mole/second, while 1 lb-mol/s equals 1632.932533 kmol/h.

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 lb-mol/s = 453.59237 mole per second (mol/s)
Step-by-step substitution for Kilomole/hour → Pound mole/second:V(lb-mol/s) = V(kmol/h) × ( 0.277778 / 453.59237 ) = V(kmol/h) × 0.000612395
Mathematical FormulaValue in Pound mole/second = Value in Kilomole/hour × 0.00061239517Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 36 kmol/h, applying the conversion factor yields exactly 0.0220462 lb-mol/s. At larger operational scale, 10000 Kilomole/hour corresponds to 6.123952 lb-mol/s.

Inverse check: 1 lb-mol/s = 1632.932533 kmol/h.
