The Gas Mileage calculator computes the average fuel economy in average miles per gallon based on the distance traveled and the fuel consumed.
INSTRUCTIONS: Choose units and enter the following:
- (D) Distance
- (F) Fuel Consumed
Fuel Economy (MPG): The calculator returns the average miles per gallon and the equivalent kilometers per liter. Note: these can be automatically converted to compatible units via the pulldown menu. The calculator also returns the mileage deduction based on the IRS rates listed below.
The Math / Science
The formula for fuel economy or average fuel efficiency is:
FE = D / F
where:
- FE = Fuel Economy or average fuel consumption
- D = Distance Traveled
- F = Fuel Consumed
This answers the questions:
- What is my average miles per gallon? MPG
- What is my average kilometers per liter? KPL
- What is my average gasoline consumption?
- What is my average petrol consumption?
- What is my average diesel consumption?

Dollar per Gallon vs Other Currencies per Liter
International travel poses a several challenges, even if it's just over the boarder to Canada or Mexico. First, there is the conversion from liters to gallons, which is fixed, and then there's the conversion between the US dollar and other currency, which is constantly changing. vCalc is here to help. We know how to do the math and we keep track of currency fluctuations, and the result makes it easier on you.
Here are four examples, US dollar per gallon from
- Euros per Liter
- Canadian Dollars per Liter
- Great Britain Pounds per Liter
- Mexican Pesos per Liter
| Country | $1.00 Equivalent | |
| Canadian Dollar | 1.396 CAD | |
| Euro | 0.954 EUR | |
| Great Britain Pound | 0.793 GBP | |
| Mexican Peso | 20.399 MXN |
The formula to convert Euros per Liter to U.S. Dollars per Gallon is:
`DPG = € EPL * (3.7854 " Liters")/(1.0 " U.S. Gallons") * ($1.0 " USD")/( "€ 0.954 EUR")`
The formula to convert Canadian Dollars per Liter to U.S. Dollars per Gallon is:
`DPG = Can$ CPL * (3.7854 " Liters")/(1.0 " U.S. Gallons") * ($1.0 " USD")/( "$ 1.396 CAD")`
The formula to convert Great Britain Pounds (Sterling) per Liter to U.S. Dollars per Gallon is:
`DPG = £ PPL * (3.7854 " Liters")/(1.0 " U.S. Gallons") * ($1.0 " USD")/( "£ 0.793 GBP")`
The formula to convert Mexican Pesos per Liter to U.S. Dollars per Gallon is:
`DPG = ₱ PPL * (3.7854 " Liters")/(1.0 " U.S. Gallons") * ($1.0 " USD")/( "₱20.399 MXN")`
where:
- DPG = US Dollars per Gallon
- € EPL = Euros per Liter
- Can$ CPL = Canadian Dollars per Liter
- £ PPL = Pounds per Liter
- ₱ PPL = Pesos per Liter
Note the currency exchange rates are updated every two minutes.
