Question 132916
You have a little problem here.  Either the guy who sold you the tank sold you a bill of goods and you really have a 137 gallon (roughly) tank, or 60.375 cm is the RADIUS, not the DIAMETER.  60.375 cm is just under 2 feet, so measure all the way across the end of the tank through the center of the circular end.  If it is about 2 feet, you have a 137 gallon tank, if it is twice that, you have a 548 gallon tank.


Whichever it is, send me an e-mail reply and I'll send you a chart.  The only other question is: Are you going to put your dipstick in with the 0 mark down and measure the depth of the fuel, or with the 0 mark up and measure the distance from the top of the tank to the surface of the fuel.  It doesn't matter, except to tell me how to arrange the axis markings on the chart.


Also let me know if you want an explanation of the mathematics, or just the chart.
