About Square Meters

A square meter (m²) is the SI derived unit of area, equal to the area of a square with sides of one meter. It is the standard worldwide for measuring room sizes, apartments, houses, and land plots. A king-size bed occupies about 4 m², a parking space is roughly 12-15 m², and a small apartment might be 50-60 m². This unit is fundamental in real estate, construction, architecture, and interior design globally.

About Square Millimeters

A square millimeter (mm²) is a metric unit of area equal to a square with sides of one millimeter. It is commonly used in precision engineering, electronics, and measuring very small surfaces such as microchips or printed circuit boards. To visualise: a typical pinhead has an area of about 2-3 mm². This unit is essential in microscopy, medical imaging, and manufacturing where tiny, precise measurements are critical.
