When converting length units, it's important to understand the different measurement systems used around the world. The metric system is used by most countries, while the imperial system is primarily used in the United States.
For rough estimates: 1 meter ≈ 3.3 feet, 1 kilometer ≈ 0.6 miles, and 1 mile ≈ 1.6 kilometers. These approximations are useful for quick mental calculations.
