Example: Inputting liquid level = 3, diameter = 24, tank length = 30, then clicking "Inches" will display the total tank volume in cubic inches and US Gallons and will also show the volume at the 3 inch level.
In addition, a dipstick chart is automatically generated.
The default dipstick chart is in increments of one but you can change that by clicking on one of the increment buttons.
An alternative to this would be inputting a different set of units. For example, if you are inputting information for a tank that is 1.25 feet in
diameter and 2 feet in length, you will end up with a default dipstick chart that has two lines  zero feet and one foot.
It would be better to input this as 15 inches and 24 inches, then clicking the "inches" button so that the default chart now has 15 lines.
The default dipstick chart increments are based on the diameter value.
