Default Rule of thumb - lbs to gal

I just came across a quick way to convert pounds to gallons. Though not as accurate as the traditional method, it does provide you with a ball park figure.

Take pounds desired, divide by 10, then add half of that number.

Example: 400 pounds = 40 + 20 = 60 gallons; 900 pounds = 90 + 45 = 135 gallons

I learned that formula almost 30 years ago flying for a commuter airline. You're right when you say that it isn't exact but it is close. I use it today when I'm running quick numbers in my head. Even if the fuel numbers are in the 100,000#'s. It still works.
