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 contains 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 flow rate in CFM (cubic feet per minute). The value must be positive. The calculator will instantly convert it to GPM (gallons per minute).
Q1: Why is the conversion factor 7.48051948051948?
A: This factor represents the number of US gallons in one cubic foot (1 ft³ = 7.48051948 gallons).
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.
Q3: What's the difference between CFM and GPM?
A: CFM measures cubic feet of fluid per minute, while GPM measures gallons of fluid per minute. They are different units for the same physical quantity - volumetric flow rate.
Q4: When would I need to convert between CFM and GPM?
A: Common applications include HVAC system design, water treatment plants, industrial processes, and when working with equipment specifications that use different measurement units.
Q5: Is this conversion accurate for both liquid and gas?
A: Yes, the conversion is purely mathematical and applies to any fluid. However, for gases, actual flow conditions (pressure, temperature) may affect the conversion in practical applications.
