1 Miles = 1.609344 Kilometres
Converted exactly through the base unit (metre) using the defined factors, for example 1 inch = 2.54 cm exactly. Shown with up to 12 significant digits.

1 mile converts to exactly 1.609344 km, and 60 mph is 96.56064 km/h. On the temperature tab, 100 degrees C is 212 degrees F, and the famous crossover point holds: minus 40 is the same in both scales.
- Data units show both decimal (KB = 1,000 bytes, as storage makers use) and binary (KiB = 1,024 bytes, as operating systems often report). Pick the one your context uses.
- Speed uses the international knot definition; volume uses US liquid measures for gallons, cups and spoons.
- Results are displayed with up to 12 significant digits so nothing is silently rounded away.
Manufacturers label capacity in decimal gigabytes (1e9 bytes) while many systems report gibibytes (2^30 bytes). The data tab converts between the two so you can compare like with like.
About this tool
The Unit Converter converts between units in eight families: length, weight, temperature, area, volume, speed, data storage and time. Every conversion runs through an exact base-unit factor (an inch is exactly 2.54 cm by definition), and temperature uses the proper offset formulas, so results are as exact as the definitions themselves.
