Where you'll actually use this
Length measurements describe how far apart two points are along a straight line. The metric system uses the meter as its base unit, while imperial systems rely on inches, feet, yards, and miles.
- Construction & DIY
Floor plans, lumber lengths, drywall sheets, and fixture clearances all swap between metric and imperial depending on supplier and region.

Convert driving distances from kilometers to miles when crossing borders or comparing routes on different map services.

Common mistakes to avoid
- Mixing up cm and m
100 cm equals 1 m. A common error is reading 1.5 m as 15 cm — always check the decimal place.
- Foot vs feet symbol
Single quote (′) means feet, double (″) means inches. 5′10″ is five feet ten inches, not feet-and-feet.
- Statute vs nautical miles
A nautical mile (1,852 m) is about 15% longer than a statute mile (1,609 m). Used for sea and air navigation.

History & context
