How to Convert Liters per Hour to m³/h
To convert liters per hour to m³/h, multiply the flow rate by the following conversion ratio: 0.001 m³/h/liters per hour.
Since one liters per hour is equal to 0.001 m³/h, you can use this simple formula to convert:
The flow rate in m³/h is equal to the flow rate in liters per hour multiplied by 0.001.
For example, here's how to convert 5 liters per hour to m³/h using the formula above.
How Many m³/h Are in a Liters per Hour?
There are 0.001 m³/h in a liters per hour, which is why we use this value in the formula above.
Our liters per hour to cubic meters per hour calculator automatically converts your flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Liters per Hour and m³/h are both units used to measure flow rate. Keep reading to learn more about each unit.
What Is a Liters per Hour?
A liters per hour is a unit of flow rate equal to 1/60 of a liters per minute (0.0166667 L/min). Equal to 1/60 L/min. [1]
The liters per hour is classified as a metric and SI-compatible unit of flow rate. Liters per Hour can be abbreviated as L/h; for example, 1 liters per hour can be written as 1 L/h.
When working with liters per hour (L/h) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, liters per hour (L/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 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. [2]
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.
When converting flow rate between liters per hour (L/h) and m³/h (m³/h), keep full floating-point precision (1 L/h = 0.001 m³/h; 1 m³/h = 1,000 L/h) during intermediate calculations and round only the final cubic meters per hour figure to match your instrument tolerance.
