Gallons per minute is the amount of gallons used or moved or saved for every minute of time that passes. If you wanted to calculate how many gallons were pumped through a water fountain every minute, you would measure this and divide the gallons by the minutes and get your "gallons per minute".

Well, gallons measure volume and kilograms measure weight. So you have to first convert gallons to liters. One gallon is 3.79 liters. Then you have to find out how much the substance you are measuring weighs per liter. For example, one liter of water weighs one kg. The divide by 60 to get minutes to seconds. So:
(3.79g*w)/60=kg per second.
With 2 pints in a quart, and 4 quarts in a gallon, there are 8 pints in a gallon.
With 60 seconds in a minute, divide that 60 seconds by the 8 seconds it would take a gallon to pass. 60/8=7.5. 1 pint per second is 7.5 gallons per minute.
Use this conversion:
gallons per minute x 0.00223 = cubic feet per second
Note: this is for US gallons.
