How to Convert cfs to m³/h
To convert cfs to m³/h, multiply the flow rate by the following conversion ratio: 101.9406477 m³/h/cubic feet per second.
Since one cubic feet per second is equal to 101.9406477 m³/h, you can use this simple formula to convert:
The flow rate in m³/h is equal to the flow rate in cfs multiplied by 101.9406477.
For example, here's how to convert 5 cfs to m³/h using the formula above.
How Many m³/h Are in a Cubic Feet per Second?
There are 101.9406477 m³/h in a cubic feet per second, which is why we use this value in the formula above.
Our cubic feet per second 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.
cfs and m³/h are both units used to measure flow rate. Keep reading to learn more about each unit.
What Is a Cubic Feet per Second?
A cubic feet per second is a unit of flow rate equal to 1,699.0107955 liters per minute (L/min), the base unit for flow rate. River hydrology flow unit equal to 28.3168 L/s. [1]
The cubic feet per second is classified as a US customary unit of flow rate. cfs can be abbreviated as ft³/s; for example, 1 cubic feet per second can be written as 1 ft³/s.
When working with cfs (ft³/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, cfs (ft³/s) are widely used across large-scale industrial, bulk, and macro-level flow rate specifications within US customary 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 cfs (ft³/s) and m³/h (m³/h), keep full floating-point precision (1 ft³/s = 101.9406477 m³/h; 1 m³/h = 0.0098096 ft³/s) during intermediate calculations and round only the final cubic meters per hour figure to match your instrument tolerance.
