Whether you're planning a road trip, shopping online for furniture, or working on a DIY project, you'll inevitably encounter different units of length. Why does one country use kilometers while another uses miles? Let's break it down.
Two Worlds: Metric vs. Imperial
The world primarily uses two systems for measuring length:
- The Metric System: This is the most common system, used by the majority of the world. It's based on the meter and uses prefixes like "kilo-" (1,000) and "centi-" (1/100th) to denote size. It's logical and easy to scale.
- The Imperial System: This system is officially used in the United States, Liberia, and Myanmar. It uses units like the inch, foot, yard, and mile.
Because these two systems exist, being able to convert between them is an essential skill.
