The abbreviation "dt" on a 20 pound propane tank typically stands for "tare weight." This refers to the weight of the tank itself without any propane in it, helping to determine the total weight when filled.
A 100-pound propane bottle can typically hold around 23.6 gallons of propane. The weight of the propane itself would be approximately 84 pounds.
100 pound propane tank will hold 23.58 gallon. 100 pounds / 4.24 pounds per gallon = 23.58 gallons

Propane burns 91,547 b.t.u.'s an hour per gallon of propane. Depending on the b.t.u. output of the appliance you are running you should be able to calculate how many hours you can use your tank.
A 100 pound propane tank can produce around 2,160,000 BTUs (British Thermal Units) of heat energy. This can vary slightly based on the quality of the propane and efficiency of the appliance using it.
You cannot use output pressure to tell how full a tank is. The pressure will remain constant until it's just about out of propane. You can use weight, if you know how much it weighs when empty, and when full - then it's just simple math.
