Multiply by 0.25: 12 (quarts per minute) x 0.25 = 3 gallons per minute (US).
Formula: quarts per minute x 15 = gallons per hour
7 quarts per minute 7 x 60 = 420 quarts per hour which is (420)/(4) = 105 gallons/hour
First, divide the gallons per second by 4 to get the number of quarts per second. Then, multiply the result (product) by 60 to get the number of quarts per minute. Example: 2 gallons per second X 4 = 8 quarts per second 8 quarts per second X 60 = 480 quarts per minute
10 US quarts per minute is 150 US gallons per hour.
Multiply quarters per minute by 15 to obtain gallons per hour. There are four quarts in a gallon, and 60 minutes in an hour. Multiplying by 60 and dividing by four is the same as multiplying by their ratio: 15.
Use this formula: gallons per minute x 3.785 = liters per minute
If there are x number of gallons per second, multiply that number by 60=gallons per minute.
8 quarts per second.
gallons per hour x 2.133 = ounces per minute
Divide the litres per minute by 4.55
60 minutes = 1 hour 6 quarts per minute = 6 x 60 = 360 quarts per hour 4 quarts = 1 gallon 360 quarts per hour = 360 / 4 = 90 gallons per hour
Multiply your gpm by 60.
