Introduction
Hey there, it’s Jamie from Useful Knowledge. Today, I want to address a common question for those of you who use propane barbecue grills or stoves – is it more cost-effective to refill your propane tank or exchange it for a new one? Join me as we break down the numbers and compare the two options.
Weighing the Tanks
I have two 20-pound propane tanks here, one that I refilled and one that I exchanged. Let’s weigh them to see how much propane each tank contains. The exchange tank weighed 33 pounds 11.6 ounces, while the refill tank weighed 36 pounds 2.2 ounces. Clearly, the refill tank has more propane, but by how much?
Calculating the Propane Content
To determine the exact amount of propane in each tank, we need to consider the tear weight of the tanks – the weight when empty. The tear weight of the refill tank is 17.1 pounds, while the exchange tank’s tear weight is 18 pounds. Let’s crunch some numbers to see how much propane is in each tank.
Comparison Chart
After converting the weights to a decimal representation for easier calculations, we found that the exchange tank contains 15.725 pounds of propane, costing $21.98 in total. On the other hand, the refill tank holds 19.038 pounds of propane, with a total cost of $16.63. The refill option clearly gives you more propane for less money.
Understanding the Discrepancy
You might be wondering why the refill tank didn’t end up with a full 20 pounds of propane. Well, there needs to be some room left for expansion in the tank, so it’s not filled to capacity. This explains the slight difference in weight between the two options.
Final Thoughts
Looking at the comparison chart, it’s evident that choosing the refill option will give you more propane at a lower cost per gallon. While the exchange route offers convenience, opting for a refill can save you money in the long run. Whether you prioritize convenience or cost-efficiency, it’s essential to weigh your options before refilling your propane tank.
