How to convert mi to km
On 1 May 1954, Roger Bannister ran the first sub-four-minute mile: 3:59.4 for 1,609.344 metres. Converted, four minutes for a mile works out to roughly 24.1 km/h average pace, a useful anchor for how the two units relate, since it is one of the few mile times widely known even outside athletics.
A quick mental estimate for driving: multiply miles by 1.6 and you land within about 0.6% of the exact answer, which is close enough for gauging a drive. 65 mph, the most common US interstate limit, is 105 km/h once converted properly, a figure worth knowing before renting a car anywhere that posts limits in kilometers per hour. Airlines and shipping, by contrast, use the nautical mile (1.852 km) instead of either the statute mile or the kilometre, a third distance unit entirely.
Frequently Asked Questions
Why is the mile-to-km conversion exact but km-to-mile is not?
⌄
The mile is defined as exactly 1,609.344 metres, so multiplying by that figure is exact. Going the other way requires dividing by it, which produces a repeating decimal that has to be rounded for display.
