How to Convert Pound mole/second to Kilomole/hour

Converting Pound mole/second (lb-mol/s) to Kilomole/hour (kmol/h) 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 Pound mole/second equals 1632.932533 Kilomole/hour, while 1 kmol/h equals 0.000612395 lb-mol/s.

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 lb-mol/s = 453.59237 mole per second (mol/s)
2. Target SI Bridge (ktarget):1 kmol/h = 0.277778 mole per second (mol/s)
Step-by-step substitution for Pound mole/second → Kilomole/hour:V(kmol/h) = V(lb-mol/s) × ( 453.59237 / 0.277778 ) = V(lb-mol/s) × 1632.932533
Mathematical FormulaValue in Kilomole/hour = Value in Pound mole/second × 1632.93253337Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 250 lb-mol/s, applying the conversion factor yields exactly 408233.133342 kmol/h. At larger operational scale, 480 Pound mole/second corresponds to 783807.616017 kmol/h.

Inverse check: 1 kmol/h = 0.000612395 lb-mol/s.
