How it works
Divide the energy in the tank by the heat the grill uses each hour. The result is the time the tank should run at that setting.
A 20 pound tank holds about 430,000 BTU of propane when full. Grills rarely run at full heat the whole time, and tank gauges read differently, so treat the result as an estimate.
Worked example
A tank holding 430,000 BTU of energy, burning at 40,000 BTU/h on high, lasts about 10 h 45 min.
Questions
How much propane is in a 20 pound tank?
A full 20 pound tank holds about 4.7 gallons of propane, which is the figure behind the default. Check the rating on your tank if it is a different size.
How do I check how much is left?
Weigh the tank on a bathroom scale and subtract the empty weight, which is usually stamped on the collar.
Why does my grill use up the tank faster?
Wind, cold weather and high heat all make a tank empty faster than the number suggests.
