Since a surface has but two dimensions, the unit of surface is a square of which the unit of length is the side. In most physical measurements the unit of surface is the square centimeter (sq. cm. or cm.²), though for small areas the square millimeter (sq. mm. or mm.*) is commonly used. The table is similar to the table for length, but with a uniform scale of 100; that is, 100 sq. mm. = 1 sq. cm., or 100 mm² = 1 cm², etc.
