  1. First of all, NEVER be without a spare tank. There is a much better way to do this. Weigh how much propane you have in the tank. The tare weight stamped on the tank, usually on the top ring near the handle. Many tanks are 18 lbs. Now measure the weight of the tank and subtract the tare weight from it. A digital luggage scale works great. Now you have the weight of the propane. You can now calculate the cooking time. There are 21600 BTUs per pound of propane. Multiply the pounds of propane by the 21600 BTUs per pound. Use your grill's owners manual or website to determine how many BTUs per hour per burner. Divide that number of BTU/hr of the burner into the number of BTUs in your remaining propane to get the number of hours remaining.

    I hope that link works.

  2. I have run out of propane before when we had guests so we ended up making a wood fire and cooking over the hot coals.   What we do now is ALWAYS have a second FULL propane tank on reserve.  We have been doing this for years and it works well.  I think I will try the method that she described in the video to see if I can judge the level of propane left…..but since I ALWAYS have my second FULL tank available….I shouldn't run into any problems if it should be empty.

  3. I used to fill propane at a gas station years ago. If you look on the collar around the valve of a propane tank, there should be two things stamped on it: Water Capacity (WC) and Tare Weight (TW). When weighing, simply take the scale reading and subtract the tare weight of the tank to get your propane level.

    Your conventional grill tank will have a water capacity of around 47.8 lbs which is 20lbs of propane (you find this number on capacity charts).

  4. You can do all of this, or you can get your fat wives' digital scale weight and weight the tank in its current state – minus the empty weight of the tank which for an average BBQ grill is 20lb, so if a pound of propane is ~4.2lb and the tank weights say, 29lb, then you know you have well over 2lb of propane in the tank which should be plenty even for a decent size cookout lasting 2-3 hours.
