Field notes
AutomotiveCalc groups its tools into five practical areas, from ownership costs and fuel economy to EV charging, tire geometry, and engine calculations. Several calculators handle unit-system differences explicitly: the MPG tool supports U.S. gallons, UK gallons, and liters, while the horsepower and torque tool accepts lb-ft, N·m, mechanical hp, kW, and metric PS. The homepage also says recently viewed inputs remain only in the current tab and are not saved.
