How to Convert m³/h to m³/s
To convert m³/h to m³/s, multiply the flow rate by the following conversion ratio: 0.000277778 m³/s/cubic meters per hour.
Since one cubic meters per hour is equal to 0.000277778 m³/s, you can use this simple formula to convert:
The flow rate in m³/s is equal to the flow rate in m³/h multiplied by 0.000277778.
For example, here's how to convert 5 m³/h to m³/s using the formula above.
How Many m³/s Are in a Cubic Meters per Hour?
There are 0.000277778 m³/s in a cubic meters per hour, which is why we use this value in the formula above.
Our cubic meters per hour to cubic meters per second calculator automatically converts your flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
m³/h and m³/s are both units used to measure flow rate. Keep reading to learn more about each unit.
What Is a Cubic Meters per Hour?
A cubic meters per hour is a unit of flow rate equal to 16.6666667 liters per minute (L/min), the base unit for flow rate. Equal to 16.6667 L/min. [1]
The cubic meters per hour is classified as a metric and SI-compatible unit of flow rate. m³/h can be abbreviated as m³/h; for example, 1 cubic meters per hour can be written as 1 m³/h.
When working with m³/h (m³/h) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, m³/h (m³/h) are widely used across standard flow rate applications within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Cubic Meters per Second?
A cubic meters per second is a unit of flow rate equal to 60,000 liters per minute (L/min), the base unit for flow rate. Coherent SI flow unit equal to 1,000 L/s (60,000 L/min). [2]
The cubic meters per second is classified as an International System of Units (SI) unit of flow rate. m³/s can be abbreviated as m³/s; for example, 1 cubic meters per second can be written as 1 m³/s.
When working with m³/s (m³/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, m³/s (m³/s) are widely used across large-scale industrial, bulk, and macro-level flow rate specifications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting flow rate between m³/h (m³/h) and m³/s (m³/s), keep full floating-point precision (1 m³/h = 0.000277778 m³/s; 1 m³/s = 3,600 m³/h) during intermediate calculations and round only the final cubic meters per second figure to match your instrument tolerance.
