What is Square Millimeter?

The square millimeter is a unit of area equal to a square with sides of one millimeter, or one-millionth of a square meter. It is most commonly used in electrical engineering to specify the cross-sectional area of wire conductors (for example, "a 2.5 mm² cable"). Precision-machined parts, O-ring cross-sections, and microelectronic chip features are also measured in square millimeters. In printing, the fine details of typefaces may be analyzed at this scale.

What is Hectare?

The hectare is a unit of area equal to 10,000 square meters, or a square 100 meters on each side. It is the most common unit for reporting agricultural land area worldwide. One hectare is roughly the size of 1.4 soccer fields or 2.47 acres. National parks, vineyards, and urban green spaces are often described in hectares. Although not an official SI unit, the hectare is accepted for use with the SI and is recognized by the International Bureau of Weights and Measures.
