How to Convert Mol/day to Pound mole/second

Converting Mol/day (mol/d) 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 Mol/day equals 2.551647 × 10⁻⁸ Pound mole/second, while 1 lb-mol/s equals 3.919038 × 10⁷ mol/d.

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 mol/d = 1.157407 × 10⁻⁵ 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 Mol/day → Pound mole/second:V(lb-mol/s) = V(mol/d) × ( 1.157407 × 10⁻⁵ / 453.59237 ) = V(mol/d) × 2.551647 × 10⁻⁸
Mathematical FormulaValue in Pound mole/second = Value in Mol/day × 2.55164655 × 10⁻⁸Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 36 mol/d, applying the conversion factor yields exactly 9.185928 × 10⁻⁷ lb-mol/s. At larger operational scale, 480 Mol/day corresponds to 1.22479 × 10⁻⁵ lb-mol/s.

Inverse check: 1 lb-mol/s = 3.919038 × 10⁷ mol/d.
