Units explained
Kanal
A kanal is a unit of land area used in Punjab, Haryana, and Pakistani Punjab, equal to approximately 505.857 m² (1/8 of an acre or 605 square yards).
Defined as 1/8 of an acre during British colonial administration of Punjab. 8 kanals make 1 acre; 20 marlas make 1 kanal.
Kanals are the primary unit for residential property in Punjab (India and Pakistan), Haryana, Jammu and Kashmir, and Himachal Pradesh. Property listings typically use kanal and marla units alongside square feet.
Standardized in colonial Punjab.
Square Millimeter
A square millimeter is a metric unit of area equal to 10⁻⁶ m² (1 mm × 1 mm). It is widely used in engineering, electronics, and small-scale technical work.
Derived by squaring the millimeter, defined as 1/1000 of a meter. The milli- prefix comes from the Latin 'mille' (thousand).
Square millimeters express PCB trace cross-sections, the area of small mechanical features in CAD drawings, biological sample sizes, and material thicknesses.
Millimeter has been part of the metric system since 1795.
