Hi,
these two are two different measurements, one determines how much you use per hour and the other how much you use per mile. To convert, you need to know how fast you are going in mph.
Example:
If you are going 50mph and use 10gph, you diviide the miles driven in one hour on the gallons used in an hour, 50mph/10gph = 5 mpg, as you can see the h goes away as the value is equal giving h/h=1 and therefore it is removed.
Doing it the other way around will give you the gallons per mile, 10gph/50mph = 0,2 gpm.

You will need to know the miles per hour being traveled. 7 mpg at 70 mph would give 10 gallons per hour. 7 mpg at 42 mph is 6 gallons per hour. 7 mpg at 7 mph is 1 gallon per hour.
Cubic feet per hour x 7.48 = gallons per hour
Divide gallons per day by 24.
gallons per hour x 2.133 = ounces per minute
Multiply your gpm by 60.
The first step is to convert fluid ounces into gallons then multiply that by 60 to get gallons per hour:4 x 0.0078 (gallons per fl. oz.) = 0.0312 gallons per minuteNext:0.0312 x 60 = 1.9 gallons per hour
Formula: quarts per minute x 15 = gallons per hour
Formula: cubic feet per hour x 7.481 = US gallons per hour (use 6.229 if you want to convert cubic feet to Imperial gallons)
Use this formula: gallons per minute x 0.227 = cubic meters per hour
To convert gallons per hour to pints per second, first convert gallons to pints by multiplying by 8 (1 gallon = 8 pints). Then convert hours to seconds by multiplying by 3600 (1 hour = 3600 seconds). Finally, divide the result in pints by the result in seconds to get pints per second.
7 quarts per minute 7 x 60 = 420 quarts per hour which is (420)/(4) = 105 gallons/hour
Use this formula: mpg x 0.4251 = km per liter.25.6 mpg x 0.4251 = about 10.88 km per liter
