About this calculator
Overview
The Gallons Per Minute (GPM) calculator is a fundamental tool used to measure flow rate. It's essential in plumbing, irrigation, fire safety, and industrial processes to ensure systems are sized correctly and operating efficiently.
💡
Pro Tips
To measure GPM manually, time how long it takes to fill a 5GL bucket.
If it takes 30 seconds to fill 5 gallons, your flow rate is 10 GPM.
Low flow rate in a home can be caused by pipe scale, a failing pressure regulator, or local utility issues.

Fun Facts
"A typical household showerhead uses between 2.0 and 2.5 GPM."
"Fire hoses can deliver anywhere from 50 to over 1,000 GPM depending on the nozzle and pressure."
"Flow rate is directly related to water pressure and the diameter of the pipe or hose."
