Miles Per Gallon Calculator

The Miles Per Gallon (MPG) Calculator helps you determine the fuel efficiency of your vehicle by calculating how many miles it can travel on one gallon of fuel. This is particularly useful for drivers who want to monitor their fuel consumption and make informed decisions about their driving habits or vehicle choices. Whether you're planning a road trip or just curious about your vehicle's performance, this calculator provides a quick and easy way to get the information you need.

To use the calculator, simply input the distance you've traveled in miles and the amount of fuel consumed in gallons. The calculator will then compute the MPG, giving you a clear picture of your vehicle's fuel efficiency. This information can help you understand how to optimize your driving for better fuel economy.

Formula

The formula used in this calculator is straightforward: MPG is calculated by dividing the total distance traveled (in miles) by the total fuel used (in gallons). This gives you the number of miles your vehicle can travel per gallon of fuel.

How to use

  1. Enter the distance traveled in miles.
  2. Input the amount of fuel used in gallons.
  3. Click the calculate button to see your MPG.

FAQ

What does MPG mean?

MPG stands for miles per gallon, which is a measure of how far a vehicle can travel on one gallon of fuel.

Why is it important to know my vehicle's MPG?

Knowing your vehicle's MPG can help you understand its fuel efficiency, allowing you to make better decisions about driving and fuel consumption.

How can I improve my vehicle's MPG?

You can improve your vehicle's MPG by maintaining proper tire pressure, reducing excess weight, and driving at moderate speeds.

FORMULA RULES (strict — the formula compiles to a single JS function the page runs):

  • Identifiers on either side MUST exactly match the camelCase names you declared in inputs/outputs.
  • Every output[].name MUST appear on the LEFT side of a "name = expression" line.
  • Use ^ for powers (e.g. (1+r)^n) OR pow(x, y).
  • Allowed math functions: sqrt abs sin cos tan log ln exp pi pow min max round floor ceil sign random.
  • No comments, no "where ..." clauses, no if/else/ternary, no string outputs, no Σ, no subscripts, no arrays, no recursion.
  • Single-step computation only. If conditional logic is needed, use boolean arithmetic: (cond > 0) exprA + (cond <= 0) exprB.
  • The bug context lists what the legacy version got wrong. FIX IT.
  • 2-5 inputs typical; outputs are plain numbers.
