You need to measure the diameter of the tank as well.

The formula to calulate the volume of the remaining fluid inside the cylindrical tank is:

π(d/2)²h, where π = 3.14, d - diameter of the cylindrical tank, and h - the height of the "remaining fluid inside the tank".

The following calculator allows you to enter the measurement in inches and calculate the volume of a cylinder in various units, including US gallons:

That formula works for a vertical cyclinder.

A lot of home tanks are horizontal cylinders, and the formula is much messier. It was in a prior thread here however,
