About the Mileage Calculator
This Mileage Calculator computes the distance, estimated travel time, and fuel use between two locations. Enter a starting point and a destination to get results in miles or kilometers. It helps you plan trips and budget fuel costs.
Distance between coordinates follows the haversine formula, the standard method for great-circle distance on a sphere. Travel time comes from dividing distance by your average speed, and fuel use comes from dividing distance by your vehicle's mileage rating. The calculator needs both locations plus an average speed and a miles-per-gallon or liters-per-100-km figure. Use a realistic average speed for your route type, since highways and city streets differ widely.
- Type your starting location and destination into the input fields.
- Enter your average speed and your vehicle's fuel efficiency.
- Read the distance, travel time, and fuel estimate, then adjust inputs to compare options.
