CFM to GPM Conversion Formula:
| From: | To: |
CFM (Cubic Feet per Minute) to GPM (Gallons per Minute) conversion is used to convert volumetric flow rates between different measurement systems. This conversion is essential in fluid dynamics, HVAC systems, and industrial applications where flow rates need to be expressed in different units.
The calculator uses the conversion formula:
Where:
Explanation: Since 1 cubic foot equals approximately 7.48052 gallons, multiplying CFM by this factor converts the flow rate to gallons per minute.
Details: Accurate flow rate conversion is crucial for system design, pump selection, pipe sizing, and ensuring compatibility between different measurement standards used in various industries and countries.
Tips: Enter the CFM value (must be greater than 0). The calculator will automatically compute the equivalent flow rate in gallons per minute with high precision.
Q1: Why is the conversion factor 7.48051948051948?
A: This factor represents the number of US liquid gallons in one cubic foot (exactly 7.48051948051948 gallons/ft³).
Q2: Does this conversion work for all fluids?
A: Yes, this is a volumetric conversion that works for any fluid, as it converts volume per time regardless of the fluid's density or viscosity.
Q3: When is CFM to GPM conversion commonly used?
A: Commonly used in water treatment, irrigation systems, chemical processing, and when converting between imperial and US customary units in fluid systems.
Q4: Are there different conversion factors for different gallon definitions?
A: Yes, this calculator uses US liquid gallons. For imperial gallons (UK), the conversion factor would be approximately 6.2288.
Q5: How accurate is this conversion?
A: The conversion is mathematically exact based on the defined relationship between cubic feet and US gallons.
