How to Convert CFH to m³/s
To convert cfh to m³/s, multiply the flow rate by the following conversion ratio: 0.000007866 m³/s/cubic feet per hour.
Since one cubic feet per hour is equal to 0.000007866 m³/s, you can use this simple formula to convert:
The flow rate in m³/s is equal to the flow rate in cfh multiplied by 0.000007866.
For example, here's how to convert 5 cfh to m³/s using the formula above.
How Many m³/s Are in a Cubic Feet per Hour?
There are 0.000007866 m³/s in a cubic feet per hour, which is why we use this value in the formula above.
Our cubic feet 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.
CFH and m³/s are both units used to measure flow rate. Keep reading to learn more about each unit.
What Is a Cubic Feet per Hour?
A cubic feet per hour is a unit of flow rate equal to 0.4719474 liters per minute (L/min), the base unit for flow rate. Gas meter flow unit (0.47195 L/min). [1]
The cubic feet per hour is classified as a US customary unit of flow rate. CFH can be abbreviated as CFH; for example, 1 cubic feet per hour can be written as 1 CFH.
When working with cfh (CFH) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, cfh (CFH) are widely used across standard flow rate applications within US customary 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 cfh (CFH) and m³/s (m³/s), keep full floating-point precision (1 CFH = 0.000007866 m³/s; 1 m³/s = 127,132.8001974 CFH) during intermediate calculations and round only the final cubic meters per second figure to match your instrument tolerance.
