How to Convert Liters per Second to CFH
To convert liters per second to cfh, multiply the flow rate by the following conversion ratio: 127.1328002 cfh/liters per second.
Since one liters per second is equal to 127.1328002 cfh, you can use this simple formula to convert:
The flow rate in cfh is equal to the flow rate in liters per second multiplied by 127.1328002.
For example, here's how to convert 5 liters per second to cfh using the formula above.

What Is a Liters per Second?
A liters per second is a unit of flow rate equal to 60 liters per minute (L/min), the base unit for flow rate. Equal to 60 L/min. [1]
The liters per second is classified as a metric and SI-compatible unit of flow rate. Liters per Second can be abbreviated as L/s; for example, 1 liters per second can be written as 1 L/s.
When working with liters per second (L/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, liters per second (L/s) are widely used across standard flow rate applications within SI metric workflows, engineering documentation, and technical data sheets.
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). [2]
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.
When converting flow rate between liters per second (L/s) and cfh (CFH), keep full floating-point precision (1 L/s = 127.1328002 CFH; 1 CFH = 0.0078658 L/s) during intermediate calculations and round only the final cubic feet per hour figure to match your instrument tolerance.
