Flow Rate Conversion Relationship
The flow rate in cubic meters per hour (m³/h) can be converted from gallons per minute (GPM) using the following formula:
m³/h = GPM × 0.22712470704
Flow Rate Input:
Flow rate measures the volume of fluid passing through a point per unit time. Common units include:
- GPM (Gallons per Minute): Used widely in the US for plumbing and irrigation.
- GPH (Gallons per Hour): Common for slower flow systems.
- L/min (Liters per Minute): Metric unit for medium flow rates.
- L/s (Liters per Second): Metric unit for high flow rates.
- L/h (Liters per Hour): Metric unit for low flow rates.
- m³/h (Cubic Meters per Hour): Standard metric unit for industrial applications.
- m³/s (Cubic Meters per Second): Used for very large flow rates.
- CFM (Cubic Feet per Minute): Common in HVAC and gas flow systems.
Practical Applications
This converter is useful in various fields:
- Irrigation: Convert GPM from sprinkler systems to m³/h for water management.
- HVAC: Convert CFM to m³/h for air flow calculations.
- Industrial: Standardize flow rates across metric and imperial units.
Example Calculation
If the flow rate is 50 GPM, the conversion to m³/h would be:
m³/h = 50 × 0.22712470704 = 11.3562 \, \text{m³/h}
Similarly:
- m³/min = 11.3562 ÷ 60 = 0.1893 m³/min
- L/h = 11.3562 × 1000 = 11356.2 L/h
- CFM = (11.3562 ÷ 60) ÷ 0.028316846592 ≈ 6.677 CFM
