Length conversions explained
Length units measure distance. The metric system uses millimeters, centimeters, meters, and kilometers. In the U.S., feet, inches, and miles are common for everyday use.
A quick reference: 1 meter equals about 3.28084 feet, and 1 mile equals about 1.60934 kilometers.
Quick tips
- Be careful with mm vs cm vs m (10 mm = 1 cm, 100 cm = 1 m).
- Miles and kilometers are close but not the same (1 mi ≈ 1.609 km).
- If you’re converting for travel, round to a sensible precision.
