Filling a 200-pound Propane Tank in Alberta: Understanding Volume and Pricing

Introduction

Propane, a commonly used gas for heating, cooking, and other domestic purposes in regions such as Alberta, Canada, is sold primarily by weight. A 200-pound tank is quite popular, holding approximately 46 gallons (174 liters) of the gas. However, understanding the pricing and volume considerations is crucial for accurate budgeting.

Calculating Costs Based on Volume

Let's consider the situation in Alberta, where propane is priced at CDN$1.26 per liter. To determine the cost of filling a 200-pound propane tank, we start with the volume conversion.

A 200-pound tank holds 46 gallons, which converts to 174 liters. Assuming a price of CDN$1.26 per liter, the total cost to fill the tank would be calculated as follows:

174 liters x CDN$1.26 per liter CDN$219.24

However, it's important to note that this cost is based on the volume of the tank, not its actual weight. Users should be aware that the weight of propane in a tank can vary due to its variable density, which can range from 0.52 to 0.58 kg/L.

Propane Density Considerations

The density of propane can vary, which means that a 200-pound tank might contain slightly more or less propane than is being charged. This is a significant factor to consider when purchasing propane by volume instead of weight.

Suppliers typically measure propane by weight, using a scale to ensure accurate pricing. For example, if a 200-pound tank is filled to the brim, it might contain as much as 10 pounds more or less than the weight being charged for, depending on the density at the time of measurement. This discrepancy can lead to overcharging or undercharging the customer.

For this reason, it is crucial to purchase propane by weight, particularly when dealing with precise measurements for heating or cooking needs. Paying by the liter can result in financial discrepancies, as the amount of actual propane received might differ from the amount charged.

Conclusion and Caution

While it is possible to purchase propane by volume, it is advisable to stick to purchasing by weight for more accurate and fair pricing. Always ensure that your supplier is using accurate scales to measure the propane in your tank. Furthermore, be aware that transportation or usage for "motive purposes" may incur additional fuel taxes.

Remember, caveat emptor. Always cross-check the volume and weight to ensure you are getting the correct amount of propane for your needs.
