Frequently Asked Questions
What is the quick trick for converting kilometers to miles?
Multiply by 0.6 for a fast estimate (true factor: 0.6214). A neater trick: consecutive Fibonacci numbers approximate the ratio — 8 km ≈ 5 mi, 13 km ≈ 8 mi, 21 km ≈ 13 mi — because the golden ratio (1.618) is close to the km-per-mile factor (1.609).
Are UK miles and US miles the same?
Yes — both use the international statute mile of exactly 1,609.344 meters. The exception is the nautical mile (1,852 m), used in aviation and shipping, which is about 15% longer than a statute mile.
What is 1,000 kilometers in miles?
1,000 km × 0.621371 = 621.4 miles — roughly the driving distance from Paris to Berlin or from San Francisco to San Diego and back.
Why do the US and UK use miles when most of the world uses kilometers?
The mile descends from the Roman mille passus (1,000 paces) through English statute. The US never converted its road network, and the UK retained miles for road signs despite otherwise adopting metric. Only a handful of countries — including the US, UK, Liberia, and Myanmar — still post road distances in miles.
