How to Convert Kilomoles per Hour to Moles per Second
To convert kilomoles per hour to moles per second, multiply the molar flow rate by the following conversion ratio: 0.2777778 moles per second/kilomole per hour.
Since one kilomole per hour is equal to 0.2777778 moles per second, you can use this simple formula to convert:
The molar flow rate in moles per second is equal to the molar flow rate in kilomoles per hour multiplied by 0.2777778.
For example, here's how to convert 10 kilomoles per hour to moles per second using the formula above.
How Many Moles per Second Are in a Kilomole per Hour?
There are 0.2777778 moles per second in a kilomole per hour, which is why we use this value in the formula above.
Our kilomole 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.
Kilomoles 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 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 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 kilomoles per hour (kmol/h) and moles per second (mol/s), keep full floating-point precision (1 kmol/h = 0.2777778 mol/s; 1 mol/s = 3.6 kmol/h) during intermediate calculations and round only the final mole per second figure to match your instrument tolerance.
