How to Convert Pound-moles per Hour to Moles per Second

To convert pound-moles per hour to moles per second, multiply the molar flow rate by the following conversion ratio: 0.1259979 moles per second/pound-mole per hour.

Since one pound-mole per hour is equal to 0.1259979 moles per second, you can use this simple formula to convert:

moles per second = pound-moles per hour × 0.1259979

The molar flow rate in moles per second is equal to the molar flow rate in pound-moles per hour multiplied by 0.1259979.

For example, here's how to convert 5 pound-moles per hour to moles per second using the formula above.

moles per second = (5 lbmol/h × 0.1259979) = 0.6299894 mol/s

How Many Moles per Second Are in a Pound-mole per Hour?

There are 0.1259979 moles per second in a pound-mole per hour, which is why we use this value in the formula above.

1 lbmol/h = 0.1259979 mol/s|1 mol/s = 7.9366414 lbmol/h

Our pound-mole per hour to mole per second calculator automatically converts your molar flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

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.
