How to Convert Moles per Hour to Moles per Second
To convert moles per hour to moles per second, multiply the molar flow rate by the following conversion ratio: 0.000277778 moles per second/mole per hour.
Since one mole per hour is equal to 0.000277778 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 moles per hour multiplied by 0.000277778.
For example, here's how to convert 5 moles per hour to moles per second using the formula above.
How Many Moles per Second Are in a Mole per Hour?
There are 0.000277778 moles per second in a mole per hour, which is why we use this value in the formula above.
Our 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.
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 Mole per Hour?
A mole per hour is a unit of molar flow rate equal to 1/3,600 of a mole per second (0.000277778 mol/s). Equal to 1/3600 mol/s. [1]
The mole per hour is classified as a metric and SI-compatible unit of molar flow rate. Moles per Hour can be abbreviated as mol/h; for example, 1 mole per hour can be written as 1 mol/h.
When working with moles per hour (mol/h) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, moles per hour (mol/h) are widely used across fine-tolerance laboratory, analytical, and micro-scale molar flow rate measurements 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 moles per hour (mol/h) and moles per second (mol/s), keep full floating-point precision (1 mol/h = 0.000277778 mol/s; 1 mol/s = 3,600 mol/h) during intermediate calculations and round only the final mole per second figure to match your instrument tolerance.
