Question

I have a propane cylinder that has written on it in large letters "11kg", but I have weighed the cylinder and it's 20 kg. Is there 9 kg of propane left?

Community Answer

If the "11kg" appears after "TW" (for tare weight), then you are correct. The tare weight is the weight of the tank when empty.

Question

How many pounds does it take to make a gallon?

Community Answer

You cannot convert pounds to gallons unless you know the density of the liquid. Let's assume you have a pound's worth of a solution, and this solution weighs one fourth of a pound for every quart. Convert the pounds to quarts and convert the quarts to gallons.

Question

How do I convert pounds to gallons for propane?

Community Answer

First, find the name of the compressed gas you want to convert. If you know the quantity in pounds, multiply by the number in Column A 3. If you know the quantity in gallons, multiply by the number in Column B 4.

Question

How old is my propane tank?

Community Answer

The age can be determined by the hydro date stamped on the tank collar. All gas cylinders are hydro tested at manufacture.
