Fuel Consumption
Engine and Performance
Understand your vehicle's performance with accurate power and torque conversions.
Speed
Convert km/h to mph and vice versa. Essential for international travel and vehicle imports.
Engine Power
Convert Horsepower (hp), Horsepower (hp) and Kilowatts (kW). Compare engine power globally.
Torque
Convert Newton-meter (Nm) and Pound-foot (lb-ft). Fundamental for engine adjustments and technical specifications.
Tires and Maintenance
Tire Calculator
Calculate the actual diameter, sidewall height and circumference of the tire from the measurement (ex: 205/55R16).
Maintenance Interval
Calculate when you reach the next maintenance interval based on current km and monthly average.
Electric Vehicles (EV)
Maximize the efficiency of your electric car with our specialized calculators.
Battery Capacity
Convert Ampere-hours (Ah) to Watt-hours (Wh) and vice versa. Understand the real capacity of your battery.
EV range (WLTP/Inmetro)
Compare electric vehicle range between WLTP, EPA, Inmetro and NEDC standards to estimate real range in different scenarios.
Economy: Electric vs Combustion
Calculate monthly and annual savings when migrating from a combustion car to an electric car considering consumption, energy tariffs and fuel prices.
Cooldown
Estimate battery recharge time based on capacity, state of charge, and AC or DC charger power.
Efficiency (km/kWh ↔ MPGe)
Convert energy efficiency metrics between km/kWh, Wh/km and MPGe to compare electric vehicle performance.
