The UK uses a mix of metric and imperial measurements for length. Road signs are in miles, but most official measurements are metric (metres, centimetres). This can be confusing, which is why this Calculator Site tool is so useful. It handles all common length units to give you quick and accurate results.

Pro Tip: Metric vs. Imperial
The metric system (metres, kilos) is based on multiples of 10, making it simple and logical. The imperial system (inches, feet, pounds) has historical roots with less regular conversions (e.g., 12 inches in a foot, 3 feet in a yard). Most of the world uses the metric system.
Here are a few key conversion factors to help you get a feel for the relationship between common metric and imperial units.
