Engine Horsepower Calculator
Calculate power from torque and RPM, or explore empirical quarter-mile horsepower estimates from elapsed time or measured trap speed.
EV vs Petrol Cost Calculator
Compare EV and petrol ownership costs using purchase price, fuel or charging, mileage, maintenance, insurance, charging losses, and final resale values.
Fuel Cost Calculator
Estimate trip fuel and cost using metric, US or independently selected units for distance, fuel economy and pump price.
Gas Mileage Calculator
Measure observed fuel economy from distance and fuel used, or compare odometer readings and fuel cost with consistent fill-up assumptions.
Horsepower Calculator
Calculate power from torque or work, and convert mechanical, metric, electric and boiler horsepower with explicit unit definitions.
Mileage Calculator
Find driving distance and estimated journey time between places or coordinates using OpenStreetMap roads.
Tire Size Calculator
Compare nominal tire dimensions and speedometer effects, or estimate the aspect ratio needed for a different rim at the same diameter.
Comparing travel and vehicle measurements
A trip cost combines distance, fuel consumption, and price. Driving-route mileage comes from a mapped route, while a geometric distance uses a different model. Vehicle measurement tools answer separate questions about power or dimensions. Choose the quantity needed before combining results from several tools.
Check units and the time or journey interval behind each measurement. Fuel economy can vary with conditions, a route provider can choose a different road, and a nominal tire size does not establish complete vehicle compatibility. Use the stated assumptions to understand the estimate's limits.

|---|---|---|
| Fuel Cost Calculator Metric trip |
| Liters = distance×consumption/100. Cost = liters×price. How it works |
| Mileage Calculator Driving route |
| Road distance comes from a routed path on the OpenStreetMap road network; miles = meters / 1609.344. How it works |
