For me I would convert to cubic feet and then to gallons. 30" : 2.5 ft 18" : 1.5 ft 6". : 0.5 ft Multiply all to get 1.875 cubic feet volume water is 7.48 gallons per cubic foot volume so 7.48 x 1.875 is 14.025 gallons
You would convert rainfall into inches and then into gallons per minute by using a series of calculations. You first ned to determine how much rain is falling in inches by collecting it in a container.
There is no direct conversion between inches and gallons because one is a unit of length and the other is a unit of volume. However, if you are looking to convert fuel efficiency from miles per gallon (mpg) to inches per gallon (in/gal), you would need additional information such as the diameter of the fuel line or nozzle.
