L/min to CFM (L/min to CFM)
Result
0.03531466672 CFM
Formula
CFM = L/min × 0.03531466672
1 L/min = 0.03531466672 CFM, and 1 CFM = 28.31684659 L/min.
Standard gravity is defined as exactly 9.80665 m/s². Density and flow factors follow from the length, mass and volume definitions (for example 1 US gallon per minute = 3.785411784 L/min).
Worked examples
- 1 L/min × 0.03531466672 = 0.035314667 CFM
- 10 L/min × 0.03531466672 = 0.35314667 CFM
- 100 L/min × 0.03531466672 = 3.5314667 CFM
Common mistakes
- Actual gravity varies from about 9.78 m/s² at the equator to 9.83 m/s² at the poles; "g" here is the defined standard value.
- GPM here means US gallons per minute; UK pump literature may use imperial gallons (4.546 L).
