Pound-moles per Hour and moles per second are both units used to measure molar flow rate. Keep reading to learn more about each unit.
What Is a Pound-mole per Hour?
A pound-mole per hour is a unit of molar flow rate equal to 0.1259979 moles per second (mol/s), the base unit for molar flow rate. US chemical engineering molar flow unit (≈ 0.126 mol/s). [1]
The pound-mole per hour is classified as a US customary unit of molar flow rate. Pound-moles per Hour can be abbreviated as lbmol/h; for example, 1 pound-mole per hour can be written as 1 lbmol/h.
When working with pound-moles per hour (lbmol/h) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, pound-moles per hour (lbmol/h) are widely used across standard molar flow rate applications within US customary workflows, engineering documentation, and technical data sheets.
What Is a Mole per Second?
SI unit of molar flow rate. It serves as a primary reference unit for measuring molar flow rate across scientific and practical applications. [2]
The mole per second is classified as an International System of Units (SI) unit of molar flow rate. Moles per Second can be abbreviated as mol/s; for example, 1 mole per second can be written as 1 mol/s.
As the primary coherent reference unit for molar flow rate in this category, all other molar flow rate units are mathematically anchored to the mole per second (mol/s).
In practice, moles per second (mol/s) are widely used across standard molar flow rate applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting molar flow rate between pound-moles per hour (lbmol/h) and moles per second (mol/s), keep full floating-point precision (1 lbmol/h = 0.1259979 mol/s; 1 mol/s = 7.9366414 lbmol/h) during intermediate calculations and round only the final mole per second figure to match your instrument tolerance.
