This useful tool will tell you how much volume is in your tanks. This tool works for Spherical, Rectangular, Vertical Flat, Vertical Cylindrical, Horizontal Flat, and Horizontal Cylindrical tanks. Also, you can see a "strap chart" to see what the depth is at every location. This is version 1.0 and is currently only english units. Next version will feature metric units as well.
