Flow Rate Converter
Convert volumetric flow among L/s, L/min, m³/h, and US gpm using L/s as the reference.
How to use
- Enter volumetric flow and choose the two units used by your pump or meter from L/s, L/min, m³/h, and US gpm.
Capabilities and scope
Compare fluid volume passing per unit time across different volume and time units.
How it works
L/s is the reference: L/min=1/60 L/s, m³/h≈0.277777778 L/s, and US gpm≈0.0630901964 L/s.
Example
1 m³/h is about 0.277778 L/s or 4.40287 US gpm.
Useful for
- Compare pump ratings in m³/h and L/min
- Convert US gpm specifications to SI
- Express low flows in L/s
Before you use it
- Mass flow is a different quantity; density is required for volume-to-mass flow conversion.
- The gpm option means US gallons per minute.

Frequently asked questions
Can I convert m³/h directly to kg/s?
Not without fluid density, so this volumetric-flow converter cannot do that by itself.
