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 particularly important in fluid dynamics, HVAC systems, and industrial applications where flow rates need to be expressed in different units.
The conversion uses the following formula:
Where:
Explanation: One cubic foot contains approximately 7.48 gallons, so multiplying CFM by this factor converts the flow rate to gallons per minute.
Details: Accurate flow rate conversion is essential for system design, pump selection, pipe sizing, and ensuring proper fluid handling in various engineering applications. Different industries and regions use different measurement units, making conversion necessary for international projects and equipment specifications.
Tips: Enter the CFM value in cubic feet per minute. The value must be positive. The converter will automatically calculate the equivalent flow rate in gallons per minute.
Q1: Why is the conversion factor 7.48051948051948?
A: This factor represents the number of US 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: What's the difference between CFM and GPM?
A: CFM measures volumetric flow rate in cubic feet, while GPM measures in gallons. Both are rate measurements but use different volume units.
Q4: When would I need to convert CFM to GPM?
A: Common applications include HVAC system design, water treatment plants, hydraulic systems, and when working with equipment specifications that use different measurement systems.
Q5: Is this conversion accurate for engineering calculations?
A: Yes, the conversion factor is precise and suitable for engineering applications. However, always verify unit requirements for specific projects.
