How to Convert Kilomoles per Hour to Kilomoles per Second

To convert kilomoles per hour to kilomoles per second, multiply the molar flow rate by the following conversion ratio: 0.000277778 kilomoles per second/kilomole per hour.

Since one kilomole per hour is equal to 0.000277778 kilomoles per second, you can use this simple formula to convert:

kilomoles per second = kilomoles per hour × 0.000277778

The molar flow rate in kilomoles per second is equal to the molar flow rate in kilomoles per hour multiplied by 0.000277778.

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

kilomoles per second = (5 kmol/h × 0.000277778) = 0.0013889 kmol/s

How Many Kilomoles per Second Are in a Kilomole per Hour?

There are 0.000277778 kilomoles per second in a kilomole per hour, which is why we use this value in the formula above.

1 kmol/h = 0.000277778 kmol/s|1 kmol/s = 3,600 kmol/h

Our kilomole 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.

Kilomoles 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 Kilomole per Hour?

A kilomole per hour is a unit of molar flow rate equal to 0.2777778 moles per second (mol/s), the base unit for molar flow rate. Chemical plant molar throughput unit (0.27778 mol/s). [1]

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

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

In practice, kilomoles per hour (kmol/h) are widely used across standard molar flow rate applications within SI metric 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 kilomoles per hour (kmol/h) and kilomoles per second (kmol/s), keep full floating-point precision (1 kmol/h = 0.000277778 kmol/s; 1 kmol/s = 3,600 kmol/h) during intermediate calculations and round only the final kilomole per second figure to match your instrument tolerance.
