1. What is Propane kWh per Gallon Calculator?

Definition: This calculator estimates the electrical energy equivalent (in kWh) that can be produced from one gallon of propane.

Purpose: It helps compare propane energy content with electricity and estimate generator output or heating potential.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E_{kWh} \) — Energy output (kWh per gallon)
• \( CV_{propane} \) — Calorific value of propane (MJ/L)
• \( \eta \) — System efficiency factor (0-1)
• 3.785 — Conversion from liters to gallons
• 3.6 — Conversion from MJ to kWh

Explanation: The formula converts propane's energy content to kWh while accounting for system efficiency.

3. Importance of Propane Energy Calculation

Details: Understanding propane's energy equivalent helps in sizing generators, estimating fuel costs, and comparing energy sources.

4. Using the Calculator

Tips: Enter the propane calorific value (default 25.3 MJ/L) and system efficiency (default 0.9 for 90%). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical calorific value for propane?
A: Propane typically has 25.3 MJ/L, but this can vary slightly based on composition and additives.

Q2: How does efficiency affect the result?
A: Higher efficiency means more usable energy. 0.9 represents 90% of the theoretical energy being utilized.

Q3: Why convert to kWh?
A: kWh is the standard unit for electrical energy, making it easier to compare with electric appliances.

Q4: What's the typical output per gallon?
A: With default values, about 25 kWh per gallon (equivalent to running a 1kW device for 25 hours).

Q5: Can I use this for other fuels?
A: The formula works for any fuel if you know its calorific value, but the constants are specific to liquid propane.
