as a private-party value, a range, or a trade-in figure - from the retention rates and adjustments you supply.Cost Gas CalculatorComputes the fuel needed and its cost for a journey from distance, fuel economy and fuel price, in either US or metric units, and can solve instead for the fuel volume alone, the economy achieved, the distance a tank covers, or the fuel price a known spend implies.Cost Petrol CalculatorComputes the fuel needed and its cost for a journey from distance, fuel economy and fuel price, in either US or metric units, and can solve instead for the fuel volume alone, the economy achieved, the distance a tank covers, or the fuel price a known spend implies.Gas Pricing CalculatorComputes the fuel needed and its cost for a journey from distance, fuel economy and fuel price, in either US or metric units, and can solve instead for the fuel volume alone, the economy achieved, the distance a tank covers, or the fuel price a known spend implies.Petrol Amount CalculatorComputes the fuel needed and its cost for a journey from distance, fuel economy and fuel price, in either US or metric units, and can solve instead for the fuel volume alone, the economy achieved, the distance a tank covers, or the fuel price a known spend implies.Auto Worth CalculatorProjects a vehicle's value over time using a declining-balance depreciation model, showing the loss in each year, and estimates what a vehicle of a given age is worth today - as a private-party value, a range, or a trade-in figure - from the retention rates and adjustments you supply.Afford Car CalculatorTurns a maximum monthly car payment, an interest rate and a loan term into the largest amount that can be financed, and the vehicle price that supports once cash down, a net trade-in and the taxes and fees rolled into the loan are included.Gas Use CalculatorComputes the fuel needed and its cost for a journey from distance, fuel economy and fuel price, in either US or metric units, and can solve instead for the fuel volume alone, the economy achieved, the distance a tank covers, or the fuel price a known spend implies.Offset Wheel CalculatorCompares two wheel widths and offsets to show how far the inner and outer rim edges move, converts between offset (ET) and backspacing, and reports the change in track width.Axle Ratio CalculatorComputes a gear pair or train ratio from tooth counts with output speed and torque, and the vehicle overall ratio, tyre diameter from the size code, road speed at an engine speed and engine speed at a road speed using exact NIST unit constants.CA DMV Fee CalculatorEstimates what a vehicle registration will cost: the value-based licence fee computed from the vehicle value and California’s statutory depreciation schedule, plus the flat registration, highway patrol, transportation and county fees taken from the current DMV fee chart.DMV Fee CalculatorEstimates what a vehicle registration will cost: the value-based licence fee computed from the vehicle value and California’s statutory depreciation schedule, plus the flat registration, highway patrol, transportation and county fees taken from the current DMV fee chart.Dr Ratio CalculatorComputes a gear pair or train ratio from tooth counts with output speed and torque, and the vehicle overall ratio, tyre diameter from the size code, road speed at an engine speed and engine speed at a road speed using exact NIST unit constants.Gear Ratio CalculatorComputes a gear pair or train ratio from tooth counts with output speed and torque, and the vehicle overall ratio, tyre diameter from the size code, road speed at an engine speed and engine speed at a road speed using exact NIST unit constants.Gearbox Ratios CalculatorComputes a gear pair or train ratio from tooth counts with output speed and torque, and the vehicle overall ratio, tyre diameter from the size code, road speed at an engine speed and engine speed at a road speed using exact NIST unit constants.Value Vehicle CalculatorProjects a vehicle's value over time using a declining-balance depreciation model, showing the loss in each year, and estimates what a vehicle of a given age is worth today - as a private-party value, a range, or a trade-in figure - from the retention rates and adjustments you supply.Silca Tire Pressure CalculatorCorrects tyre pressure for temperature and altitude using the gas law on absolute pressure, and works out how much to add or let out to hit the placard pressure at the temperature you are actually inflating in.Directions Distance CalculatorComputes the straight-line distance and initial bearing between two locations given by coordinates, estimates the road distance using a circuity factor or a road distance you supply, and turns it into a driving time.Auto Pricing CalculatorProjects a vehicle's value over time using a declining-balance depreciation model, showing the loss in each year, and estimates what a vehicle of a given age is worth today - as a private-party value, a range, or a trade-in figure - from the retention rates and adjustments you supply.Compare Tyre Sizes CalculatorConverts a metric tire code into nominal sidewall height, overall diameter, circumference and revolutions per mile, decodes the load index and speed symbol, and compares two sizes for diameter difference and speedometer error.RPM CalculatorComputes a gear pair or train ratio from tooth counts with output speed and torque, and the vehicle overall ratio, tyre diameter from the size code, road speed at an engine speed and engine speed at a road speed using exact NIST unit constants.Air Travel Time CalculatorComputes how long a journey takes from its distance and a constant average speed, adds any planned stops, and reports the arrival time and date when a departure time is given.Displacement Engine CalculatorComputes engine displacement from bore, stroke and cylinder count, reporting it in cc, litres and cubic inches, plus the swept volume of one cylinder and the compression ratio when the chamber volume is known.Used Car Purchase CalculatorTurns a maximum monthly car payment, an interest rate and a loan term into the largest amount that can be financed, and the vehicle price that supports once cash down, a net trade-in and the taxes and fees rolled into the loan are included.Car Trade Value CalculatorProjects a vehicle's value over time using a declining-balance depreciation model, showing the loss in each year, and estimates what a vehicle of a given age is worth today -
