A 10 US gpm flow
10 US gallons per minute equals 37.85411784 L/min. Over 10 minutes at that constant rate, the collected volume is 378.5411784 L.
Convert a volumetric flow rate
US liquid and Imperial gallons are separate choices. CFM means actual cubic feet per minute here, without a standard gas condition.

How to use the Flow Rate Converter
- 01
Enter a nonnegative volume flow and choose its unit. Select US liquid or Imperial gallons explicitly when using gallons per minute.
- 02
Choose the target unit. Enter run time in minutes and a positive fluid density in kg/m³ for the separate collection and mass-flow estimates.
- 03
Inspect the conversion and scenario results. Copy the selected result or download all listed volume-flow equivalents.
Examples
Airflow in CFM
100 actual cubic feet per minute equals about 169.901080 m³/h. This is a geometric unit conversion at the same conditions, not a conversion between actual and standard gas volumes.
From volume to mass flow
At 1 L/s and an entered fluid density of 1000 kg/m³, mass flow is 1 kg/s. Changing density to 800 kg/m³ changes mass flow to 0.8 kg/s while leaving every volume-flow equivalent unchanged.
Volume per time is the converted quantity
The base calculation expresses each unit in cubic meters per second, then divides by the target factor. Per-minute and per-hour units differ by their time denominator as well as their volume unit. US gallons mean liquid gallons; dry gallons are not included. Cubic feet use the international foot.
Collected volume and mass flow
At constant volumetric flow Q, collected volume is Q multiplied by elapsed time. Mass flow is Q multiplied by fluid density at the same conditions. The default density of 1000 kg/m³ is an editable reference value. It is not an automatically selected property of water, oil, gas, or another material.
Gas conditions and system behavior
A cubic meter of gas changes mass with pressure, temperature, and composition. SCFM and normal cubic meters refer to specified reference conditions, which vary by convention. This tool offers actual volume units only. It also does not use pipe diameter, pressure drop, or pump curves to infer a flow that has not been entered.
What to know
- No pipe sizing, pump performance, pressure loss, or standard-gas normalization is calculated.
- Collection assumes constant flow and the mass estimate uses your supplied density.
- Decimal and scientific notation are supported; commas and unit text are not. Calculations use JavaScript floating-point numbers and displayed results are rounded.
Common questions
Are US gpm and Imperial gpm equivalent?
No. An Imperial gallon is larger than a US liquid gallon. Both options are labeled separately, and an unchanged physical flow has different numerical values in those units.
Can I convert CFM to L/min?
Yes, for the same actual volume at the same conditions. The conversion does not normalize a gas to standard temperature or pressure.
Does density change the main conversion?
No. Volume-flow conversions depend only on volume and time factors. Density affects the auxiliary mass-flow estimate.
Is zero flow allowed?
Yes. It produces zero in the unit table, zero collected volume, and zero mass flow for valid scenario controls. Negative directional flow is outside this tool’s magnitude model.
