How to Convert Pound mole/second to Attomol/second

Converting Pound mole/second (lb-mol/s) to Attomol/second (amol/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 × 10²⁰ Attomol/second, while 1 amol/s equals 2.204623 × 10⁻²¹ 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 amol/s = 1 × 10⁻¹⁸ mole per second (mol/s)
Step-by-step substitution for Pound mole/second → Attomol/second:V(amol/s) = V(lb-mol/s) × ( 453.59237 / 1 × 10⁻¹⁸ ) = V(lb-mol/s) × 4.535924 × 10²⁰
Mathematical FormulaValue in Attomol/second = Value in Pound mole/second × 4.5359237 × 10²⁰Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 15 lb-mol/s, applying the conversion factor yields exactly 6.803886 × 10²¹ amol/s. At larger operational scale, 10000 Pound mole/second corresponds to 4.535924 × 10²⁴ amol/s.

Inverse check: 1 amol/s = 2.204623 × 10⁻²¹ lb-mol/s.
