100 miles is equal to 66.6667 miles per gallon (mpg). This means that if a vehicle can travel 100 miles using a certain amount of fuel, its efficiency is approximately 66.67 mpg. This measurement helps compare how fuel-efficient different vehicles are.
To convert miles to mpg, you must know how many miles a vehicle can travel on a gallon of fuel. Since miles is a distance and mpg is miles per gallon, the conversion involves understanding how many miles are covered per unit of fuel. For example, if a car travels 100 miles on 1.5 gallons of fuel, its mpg is 100 divided by 1.5, which equals about 66.67 mpg.

Conversion Formula
The formula for convert miles to mpg is simple: miles divided by gallons used. It works because mpg measures how many miles a vehicle can go per gallon of fuel. For example, if you travel 100 miles and use 1.5 gallons, then 100 divided by 1.5 gives 66.67 mpg. This straightforward division provides a measure of fuel efficiency.
Conversion Example
- Suppose a car travels 150 miles using 3 gallons of fuel.
- Calculate mpg by dividing 150 miles by 3 gallons.
- 150 / 3 = 50 mpg.
- This means the car gets 50 miles per gallon.
- In another case, a vehicle covers 200 miles with 4 gallons.
- 200 / 4 = 50 mpg again, showing consistent efficiency.

Conversion Definitions
Miles: A measurement of distance equal to 1,760 yards, used mainly in the United States. It indicates how far a vehicle travels over a certain route or journey.
MPG (miles per gallon): A unit that shows how many miles a vehicle can travel on one gallon of fuel. It measures fuel efficiency, with higher values indicating better fuel economy.
Conversion FAQs
How accurate is the conversion from miles to mpg using this method?
The conversion relies on dividing miles traveled by gallons used, which is precise if you know the exact fuel consumption. However, inaccuracies can occur if the fuel amount is estimated or the vehicle’s efficiency varies during the trip.
Can I convert miles to mpg without knowing the gallons used?
No, because mpg requires both miles traveled and fuel consumed. Without knowing the gallons used, you cannot accurately calculate the miles per gallon. You need both pieces of information for correct conversion.
Does this conversion work for all types of vehicles?
This calculation applies generally to any vehicle where fuel consumption is measured in miles per gallon. However, for electric vehicles or different measurement systems, alternative calculations are necessary.
What if my vehicle’s fuel efficiency varies during the trip?
In such cases, the average mpg can be calculated by dividing the total miles traveled by the total gallons used over the entire trip. Variations in efficiency can skew real-time readings but averaging provides a fair measure.
