Automotive

Driving-cost and fitment calculators with metric and imperial unit conversions built in.

Calculate the total fuel cost of a trip from distance, fuel consumption and fuel price, split per passenger and per 100km.

Convert fuel economy between L/100km, km/L, US MPG and UK MPG from distance traveled and fuel used, with the gallon size difference explained.

Tires

Compare old and new tire sizes to see the overall diameter change, speedometer effect and whether the fitment is within the ±3% guidance.
