GPD = GPM × 1440
| From: | To: |
The GPM to GPD conversion calculates the flow rate from gallons per minute to gallons per day. This conversion is essential for water management, industrial processes, and environmental monitoring where daily flow rates need to be estimated from minute-based measurements.
The calculator uses the simple conversion formula:
Where:
Explanation: Since there are 1,440 minutes in a day (24 hours × 60 minutes), multiplying the flow rate in gallons per minute by 1,440 gives the total gallons that would flow in a 24-hour period.
Details: Converting GPM to GPD is crucial for water treatment plants, irrigation systems, industrial processes, and environmental monitoring. It helps in daily volume calculations, resource planning, and regulatory compliance reporting.
Tips: Enter the flow rate in gallons per minute (GPM). The value must be positive. The calculator will automatically compute the equivalent gallons per day (GPD).
Q1: Why multiply by 1440?
A: There are 1,440 minutes in a day (24 hours × 60 minutes), so multiplying GPM by 1,440 converts minute flow to daily flow.
Q2: Can this conversion be used for other units?
A: The same principle applies to any flow rate conversion from per-minute to per-day units, but the conversion factor remains 1,440.
Q3: What are typical GPM values in residential applications?
A: Residential water systems typically range from 5-20 GPM, while irrigation systems may vary from 10-100 GPM depending on size.
Q4: How accurate is this conversion for variable flow rates?
A: This conversion assumes constant flow rate. For variable flows, average GPM over time should be used for accurate GPD estimation.
Q5: What's the difference between GPD and GPM?
A: GPM measures instantaneous flow rate, while GPD measures total volume over 24 hours. GPD is useful for daily consumption or production calculations.
