Calculate flow rate by dividing volume by time. Use this calculator for water pipes, pumps, irrigation systems, and any fluid flow measurements.
The flow rate calculator uses this formula:
Flow Rate = Volume ÷ Time
For example, if 100 gallons flow through a pipe in 10 minutes, the flow rate is 10 gallons per minute (GPM).
| GPM | Gallons Per Minute |
| LPM | Liters Per Minute |
| GPH | Gallons Per Hour |
| CFM | Cubic Feet Per Minute |
| L/s | Liters Per Second |
