Gallons per Second (GPS) to Gallons per Minute (GPM) Flow Unit Conversion Calculator

This tool provides engineers, technicians, and water system professionals with a fast and dependable way to scale flow measurements correctly for system design and performance evaluation by converting Gallons per Second (GPS) to Gallons per Minute (GPM).

Measured in U.S. gallons, Gallons per Second (GPS) is a U.S. conventional unit of flow rate indicating the volume of fluid passing a place per second. Especially in high-capacity flow systems where real-time responsiveness is crucial, it is usually employed.

  • Design and assessment of firefighting systems.
  • High-rate pump performance evaluations.
  • Surge flow measurements in municipal and industrial water systems.
  • High-speed fluid processing real-time diagnostics.

A standard U.S. flow unit, Gallons per Minute (GPM) describes the volume of fluid flowing each minute. From domestic plumbing to large-scale irrigation and industrial operations, it is often used in many different fluid control applications.

  • Residential and commercial plumbing water flow control.
  • Control and sizing of irrigation systems.
  • Industrial system pump and valve standard.
  • Measurement of cooling loop flow in mechanical and HVAC systems.

This formula will help you to change Gallons per Second (GPS) into Gallons per Minute (GPM):

Explanation: There are 60 seconds in a minute, so 1 GPS equals 60 GPM.

If your current flow is 5 GPS, convert it to GPM:

5 × 60 = 300 GPM

So, a flow rate of 5 Gallons per Second is equivalent to 300 Gallons per Minute.

  • Adjust or evaluate device capacity for different flow durations.
  • Convert fast flow data into reasonable control system setpoints.
  • Assist with equipment selection for emergency flow systems, surge tanks, or firefighting.
  • Standardize flow system documentation and reporting formats.
  • Assist pump calibration, process scaling, and troubleshooting.

This conversion tool is essential for ensuring accurate and consistent flow data when working across systems that demand either high-speed or averaged flow readings.
