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

To convert pound-moles per hour to kilomoles per second, multiply the molar flow rate by the following conversion ratio: 0.000125998 kilomoles per second/pound-mole per hour.

Since one pound-mole per hour is equal to 0.000125998 kilomoles per second, you can use this simple formula to convert:

kilomoles per second = pound-moles per hour × 0.000125998

The molar flow rate in kilomoles per second is equal to the molar flow rate in pound-moles per hour multiplied by 0.000125998.

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

kilomoles per second = (5 lbmol/h × 0.000125998) = 0.000629989 kmol/s

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

There are 0.000125998 kilomoles per second in a pound-mole per hour, which is why we use this value in the formula above.

1 lbmol/h = 0.000125998 kmol/s|1 kmol/s = 7,936.6414387 lbmol/h

Our pound-mole per hour to kilomole 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 kilomoles 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 Kilomole per Second?

A kilomole per second is a unit of molar flow rate equal to 1,000 moles per second (mol/s), the base unit for molar flow rate. Equal to 1,000 mol/s. [2]

The kilomole per second is classified as a metric and SI-compatible unit of molar flow rate. Kilomoles per Second can be abbreviated as kmol/s; for example, 1 kilomole per second can be written as 1 kmol/s.

In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilomole per second (kmol/s) a convenient decimal multiple of the mole per second (mol/s).

In practice, kilomoles per second (kmol/s) are widely used across large-scale industrial, bulk, and macro-level molar flow rate specifications within SI metric workflows, engineering documentation, and technical data sheets.

When converting molar flow rate between pound-moles per hour (lbmol/h) and kilomoles per second (kmol/s), keep full floating-point precision (1 lbmol/h = 0.000125998 kmol/s; 1 kmol/s = 7,936.6414387 lbmol/h) during intermediate calculations and round only the final kilomole per second figure to match your instrument tolerance.
