The Fuel in a Skid Tank calculator computes the content fluid (e.g. fuel) volume in an above ground circular storage tank based on the tanks dimensions and the measurement of a dipstick (see Directions).
INSTRUCTIONS: Choose units and enter the following:
- (F) Depth of Fluid in Tank (wet dipstick)
- (L) Length of Storage Tank
- (D) Diameter of Storage Tank
Content Volume (CV): The calculator returns the volume of fuel in gallons. However, this can be automatically converted to other volume units (e.g. liters, barrels) via the pull-down menu. The calculator also returns:
- (CV) Content Volume in gallons
- (TV) Volume of tank if full.
- (VtF) Volume to Fill. This is the added volume to "top up" the tank to full.
The Math / Science
This calculator answers the question, "How much is in my fuel tank?"
To compute the volume of liquid in the tank, enter a dipstick and measure the depth of the fluid (F). Then measure the dimensions of the tank (diameter and length).
ASTs are used for home heating oil, kerosene and diesel fuel. The typical AST has a cap that is used to refuel the tank. This is the easiest place to insert a dipstick (measuring stick) to measure the depth (F) of the liquid content of the AST. 
The picture shown is a hand crank that pumps 10 gallons for every 100 turns of the pump crank(See Hand Pump Volume formula). During cold periods, the fuel supplier will treat the diesel with an anti-freeze mixture, but this is only a concern if the temp is well below zero degrees F (e.g.-5 F or colder).
