Definitions of Measurement Units

Square Meter (m²): The square meter is the SI unit of area, representing a square with 1-meter sides. It is widely used in construction, real estate, and land measurement.

Square Millimeter (mm²): The square millimeter is also part of the metric system and equals the area of a square with 1-millimeter sides. It is often used in precision engineering and manufacturing.

Conversion Formula

To convert m² to mm²: Area (mm²) = Area (m²) × 1,000,000

To convert mm² to m²: Area (m²) = Area (mm²) × 0.000001
