How it works
Distance Converter: inputs, formula, and result
This flexible calculator takes a distance value in either miles or kilometers and applies the 1.60934 conversion factor as either a multiplier or divisor to produce the alternate measurement.
Formula
Kilometers = Miles × 1.609344; Miles = Kilometers × 0.621371
Worked example
360 miles = 579.36 km; 360 km = 223.69 miles.
Pro tip: When planning a European road trip with a US-spec vehicle, convert your route distance to miles first, then use your car's MPG rating to estimate fuel needed.
