Which statement about tare weight is true?

• A. It is the weight of the contents
• B. It is the weight of the cylinder empty
• C. It is the maximum allowable pressure
• D. It is the weight of the cylinder when full

Answer: (B)

Tare weight is the weight of the empty cylinder. This value is what you compare against the total weight of the cylinder when it’s filled to figure out how much propane is inside—the difference between gross (total) weight and tare weight gives you the liquid content. It’s not the weight of the contents, not the maximum pressure, and not the weight of the cylinder when full. The tare weight is often stamped on the cylinder so you can quickly determine how much propane you have by weighing the cylinder and subtracting the empty (tare) weight.
