New Zealand uses kilometres for distance and speed. Miles are used in the United States and the United Kingdom, so this converter is useful for travel and for content quoted in miles.

Km to Miles Converter

This converter switches between kilometres and miles in either direction, instantly and without any maths on your part. New Zealand measures distance and speed in kilometres, but plenty of the world, including the United States and the United Kingdom, still uses miles, so you will run into miles when reading about running and cycling records, road trip distances overseas, treadmill settings, or the range of an imported car or appliance. Type a figure into either the kilometres box or the miles box and the other updates immediately as you type, using the exact conversion factor of 0.621371 miles per kilometre, or 1.60934 kilometres per mile, so there is no rough rounding involved. Below the converter, a quick reference table lists common distances already converted, from 1 kilometre up to 160 kilometres, roughly 100 miles, which is handy for spotting the pattern at a glance rather than converting one figure at a time. Use it when planning a trip and comparing distances quoted in miles, when comparing race times or running and cycling distances from overseas events, when reading content written for a US or UK audience, or when checking the specifications of an imported vehicle, appliance or piece of equipment. Because the figures are calculated to the exact factor rather than a rough shortcut, you can trust the result for anything from casual travel planning to more precise conversions.
