Conversion details
Formula and exact relation
- 1 L/min = 0.264172052358 US gpm
- 1 US gpm = 3.785411784 L/min
Formula form: US gpm = L/min × 0.264172052358. Display rounding follows your selected precision and does not change base conversion math.
Flow
- Enter a flow value.
- Choose source and destination flow units.
- Read converted flow and swap units to verify reverse conversion.
Example
Worked example: 100 L/min to gpm
- 1 Convert to L/s: 100 ÷ 60 = 1.6667 L/s
- 2 1 US gpm = 0.0630902 L/s
- 3 1.6667 ÷ 0.0630902 = 26.42 gpm
100 L/min is approximately 26.42 gpm.
How
- Enter a flow value.
- Choose source and destination flow units.
- Read converted flow and swap units to verify reverse conversion.
Avoid
- Mixing volumetric flow with mass flow units.
- Using imperial gallon assumptions when US gallon factors are intended.
- Forgetting time-basis conversion (per minute vs per second).
Checks
Best fit
Flow Rate Converter is built for convert volumetric flow units including l/s, l/min, m³/h, gpm, and cfm. If Flow Rate Converter does not match the input scope, compare the answer with a second method.
Input check
Match the entered values to this rule before copying the answer: Q_target = Q_source × (source-to-base / target-to-base).
Sanity check
For Flow Rate Converter, use the worked example as a quick benchmark: 100 L/min is approximately 26.42 gpm. If the flow rate converter answer is far away, check whether an input, unit, or mode changed.
Before copying
Review this common issue first: mixing volumetric flow with mass flow units.
FAQ
Does this convert mass flow?
No. This tool handles volumetric flow only.
Are gallons US or imperial?
The converter uses US gallons (gpm).
Can I use this for HVAC cfm checks?
Yes. cfm is included for quick HVAC airflow unit conversion.
