1. What is the Propane Tank Usage Calculator?

The Propane Tank Usage Calculator estimates how long a propane tank will last based on tank capacity and appliance BTU consumption. It helps users plan their propane usage and anticipate refill needs.

2. How Does the Calculator Work?

The calculator uses the propane usage formula:

\[ Days = \frac{Tank\ Capacity\ (gal) \times 91,500\ BTU/gal}{Appliance\ BTU/hr \times 24} \]

Where:

Explanation: The formula calculates total available energy in the tank and divides by daily energy consumption to determine runtime in days.

3. Importance of Propane Usage Calculation

Details: Accurate propane usage estimation is crucial for planning fuel purchases, preventing unexpected outages, and budgeting for heating or cooking needs.

4. Using the Calculator

Tips: Enter tank capacity in gallons and appliance BTU consumption rate. Ensure values are positive numbers for accurate calculations.

5. Frequently Asked Questions (FAQ)

Q1: What is the energy content of propane?
A: Propane contains approximately 91,500 BTU per gallon, which is the standard value used in calculations.

Q2: How accurate is this calculation?
A: This provides an estimate. Actual usage may vary based on appliance efficiency, weather conditions, and usage patterns.

Q3: Can I use this for multiple appliances?
A: For multiple appliances, sum the BTU/hr ratings of all appliances running simultaneously and use that total in the calculation.

Q4: What are common propane tank sizes?
A: Common sizes include 20 lb (4.7 gal), 30 lb (7 gal), 40 lb (9.4 gal), and larger stationary tanks from 120-1000 gallons.

Q5: Should I include a safety margin?
A: Yes, it's recommended to plan refills when the tank reaches 20-30% capacity to avoid running out completely.
