How to Convert Pound mole/second to Femtomol/second

Converting Pound mole/second (lb-mol/s) to Femtomol/second (fmol/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 Pound mole/second equals 4.535924 × 10¹⁷ Femtomol/second, while 1 fmol/s equals 2.204623 × 10⁻¹⁸ 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 fmol/s = 1 × 10⁻¹⁵ mole per second (mol/s)
Step-by-step substitution for Pound mole/second → Femtomol/second:V(fmol/s) = V(lb-mol/s) × ( 453.59237 / 1 × 10⁻¹⁵ ) = V(lb-mol/s) × 4.535924 × 10¹⁷

Worked Example

To convert 12 Pound mole/second (lb-mol/s) to Femtomol/second (fmol/s): multiply 12 by 4.535924 × 10¹⁷ to get 5.443108 × 10¹⁸ fmol/s. At an industrial engineering scale, 480 lb-mol/s converts to 2.177243 × 10²⁰ fmol/s.

Inverse check: 1 fmol/s = 2.204623 × 10⁻¹⁸ lb-mol/s.
