In chemistry, gallons per minute are a measurement of flow rate. It is calculated by dividing the volume of a fluid in seconds by its rate of flow. The unit is most commonly used in water-related applications such as showerheads or hoses. Standard showerheads are rated at 2 gallons per minute in the US. Water-saving showerheads are rated at around half of this amount.
Another way to measure GPM is to divide the total capacity of a container by the number of seconds it takes to fill it. This can be done by using a stopwatch or simply by counting the number of seconds it takes to fill the container. The result is then divided by 60 to find the gallons per minute.
Gallons per minute is also known as volume flow rate and litres per minute (l/min). 1 US gallon per minute is equal to 3.785411784 liters per minute. See the below table for step by step unit conversion with formulas and explanations.
The SI derived unit for volume flow rate is the cubic meter per second. 1 US gallon per minute is equal to 15.850.323074494 cubic meter per second.
