Gas Price Calculator – Convert Gallons to Liters and Estimate Fuel Cost

Fuel prices vary across regions, and so do the units used for measurement. In the U.S., gasoline is usually sold in gallons, while in many other countries, fuel is measured in liters. If you want to compare prices, plan a trip abroad, or simply calculate fuel costs, a Gas Price Calculator (Gallons to Liters) can help you.

This tool allows you to convert gallons to liters and calculate the total fuel cost in both units.

Conversion Factor: Gallons to Liters

The standard conversion between U.S. gallons and liters is:

$1\text{Gallon}=3.78541\text{Liters}$​​​​​​​

Formula for Gas Price Calculator

Convert Gallons to Liters

$\text{Liters}=\text{Gallons}\times 3.78541$

Calculate Total Price

$\text{Total Price}=\text{Gallons}\times \text{Price per Gallon}$

Find Price Per Liter

$\text{Price per Liter}=\frac{\text{Price per Gallon}}{3.78541}$

Example Calculation

Suppose you purchased 10 gallons of gas at a rate of $3.50 per gallon.

Step 1: Convert gallons to liters

$\text{Liters}=10\times 3.78541=37.8541\text{L}$

Step 2: Calculate total price

$\text{Total Price}=10\times 3.50=35.00\text{ \$}$

Step 3: Find price per liter

$\text{Price per Liter}=\frac{3.50}{3.78541}\approx 0.925\text{ \$/L}$

Final Results:

• Fuel Quantity = 37.85 liters
• Total Price = $35.00
• Price Per Liter = $0.93/L
