- Exactly 10,000 m², a square 100 m on each side, and a non-SI unit accepted for use with the SI. Hectares measure farms, forests, and parks, and one hectare equals about 2.47 acres.
- Square Millimeters (mm²)
- The area of a square 1 mm on each side, or one millionth of a square meter. It is the standard size measure for electrical wire cross-sections outside North America, and it also describes camera sensors.
