What is the conversion factor from gallons per minute to gallons per day?

The conversion factor from gallons per minute to gallons per day is based on the relationship between minutes and the total minutes in a day. Since there are 60 minutes in an hour and 24 hours in a day, the total number of minutes in a day is 60 multiplied by 24, which equals 1,440 minutes.

To convert a flow rate measured in gallons per minute to a total volume over a day, you multiply the number of gallons per minute by the total number of minutes in one day (1,440). This effectively scales the flow rate up to reflect the total gallons that would accumulate over a full day of that flow rate.

Thus, when you have a measurement in gallons per minute and wish to find out how many gallons that equals in a day, the correct approach is indeed to multiply by 1,440.
