VIN decode, engine size, tire equivalents, SAE to metric wrenches, and torque conversions for salvage-yard and DIY work. All free, no account required.
Paste a 17-character VIN to look up year, make, model, engine, body style, and plant from the public NHTSA vPIC catalog. Use it at a salvage yard to confirm what a vehicle actually is before you pull parts.
Open converterConvert liters to cubic inches the way yards and listings talk. 5.7 L is 350 cid on a Chevy small-block and 345 cid on a Hemi. Type either unit and see the exact math plus common shop names.
Open converterDecode a sidewall code like 225/45R17 into section width, sidewall height, overall diameter, and revolutions per mile. Then compare close equivalents that stay within 3% diameter — same rim first, which is what you want for a wheel already in the yard.
Open converterConvert standard inch wrenches and sockets to millimeters, then see whether the closest size will actually fit. A 7/16" wrench is close to 11 mm. A 3/8" wrench on a 10 mm fastener is a mismatch that can round the corners.
Open converterConvert torque between ft-lb, N·m, in-lb, and kgf·m. Type in any box and the others follow. Use it when a shop manual, torque wrench, and fastener spec are not in the same unit.
Open converterPick a date in the past and the date of an event. The calculator shows the same span as years, months and weeks, total weeks, and exact days — useful for how long a vehicle sat, a listing age, or any two calendar dates.
