Gallon per minute is a unit that measures how fast water flows through a cross-sectional area. This calculator helps you convert gallons per minute to other units of volume, and you can also use the tool to find how many gallons your water hose delivers each minute.
GPM is commonly used to describe the flow rate of water through a pump, showerhead, or pipe. It is important to note that the amount of water flowed over a certain period of time can also be described in terms of “head,” which refers to the distance the water travels vertically, or how high it moves.
For example, standard showerheads typically have a GPM of around 2 in the US, while higher-end water-saving models can often deliver up to 5 GPM. However, this number is dependent on a variety of factors, such as water pressure, the size of the water pipe, and the amount of head the water must travel through.
If you’re measuring a specific flow rate of liquid, the easiest way to determine GPM is by using a one-gallon container and timing how long it takes to fill. Then, divide the number of seconds needed to fill the container by 60. You can also calculate GPM by taking the capacity of the container in gallons and multiplying it by the number of seconds it takes to fill (GPM = gallons / 60 / second). gallons per minute to litres per minute
