Multiply the number of cubic feet per second by 7.4805 to convert to gallons per second. For example, if you start with 42 cubic feet per second, multiply 42 by 7.4805 to get 314.181 gallons per second.
How do you calculate CFS?
Calculate the discharge in cubic feet per second (cfs) by multiplying velocity (ft/sec) by the cross-sectional area (ft2) of the stream.
How do you calculate GPM?
The formula to find GPM is 60 divided by the seconds it takes to fill a one gallon container (60 / seconds = GPM). Example: The one gallon container fills in 5 seconds. 60 / 5 = 12 GPM. (60 divided by 5 equals 12 gallons per minute.)

What is the gpm flow rate?
GPM means Gallons Per Minute. Also known as “flow rate”, GPM is a measure of how many gallons of water flow out of your shower head each minute. Since 1992, a maximum of 2.5 GPM is the federally mandated flow rate for new shower heads. This means no more than 2.5 gallons of water should flow out each minute.
What unit is gpm?
Water in motion; i.e., flowing in streams, canals, pipelines, and ditches, is measured in units of volume per unit of time—gallons per minute (gpm), cubic feet per second (cfs), acre-inches per hour and acre feet per day. Cubic feet per second, sometimes written second-feet (sec.
