The Gas Mileage calculator computes the average fuel economy 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?

Money and Travel
The US Mileage Rate for Business Travel shows the dollars per mile deduction for business travel for the calendar year. The most recently queried information from the IRS website on mileage includes:
Mileage Calendar Year: 2022
- $62.5 USD/mi: Mileage Deduction for Business Travel
- $22.0 USD/mi: Mileage Deduction for Moving or Medical Travel
- $14.0 USD/mi: Mileage Deduction for Charitable Donation Travel
Use these deductions rates in the Mileage Tax Deduction Calculator. It computes tax deductions from miles travelled. Just enter the miles traveled and see the dollar amount associates for business, moving or medical, and charitable work.
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 | 1.347 CAD | |
| Euro | 0.938 EUR | |
| Great Britain Pound | 0.814 GBP | |
| Mexican Peso | 17.198 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") * ($1.0 " USD")/( "€ 0.938 EUR")`
The formula to convert Canadian Dollars per Liter to U.S. Dollars per Gallon is:
`DPG = Can$ CPL * (3.7854 " Liters")/(1.0 " U.S. Gallons") * ($1.0 " USD")/( "$ 1.347 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")/( "£ 0.814 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") * ($1.0 " USD")/( "?17.198 MXN")`
where:
- DPG = US Dollars per Gallon
- € EPL = Euros per Liter
- Can$ CPL = Canadian Dollars per Liter
- £ PPL = Pounds per Liter
- ? PPL = Pesos per Liter
