From a mathematical or physical point of view, surfaces are two-dimensional objects or structures that have an area and a perimeter. It has at least one internal point. Historical area dimensions often have their origins in agriculture. "Daily work" was defined as the measure of the area that a farmer plowed in one day, and "man mowing" as the area that a man could mow per day. The unit "morning" or "yoke" referred to a smaller area. The "bushel seed" was the size of the area that could be tilled (planted) with the seeds that fit in a bushel (a specific container). These units of measure differed from country to country and even from city to city.

Even today there are special area measures such as hectares (ha) and ares (a) in agriculture. They can be traced back to metric units. The units of measurement of the International System SI are derived from the basic units for length - square kilometers, square meters, square decimeters, square centimeters, and square millimeters. In science they are used worldwide. Nuclear physics sometimes uses other unit designations for very small areas. In countries such as the UK and the USA, where units of length such as inches, feet and miles are still used, there are square inches, square feet and square miles, respectively.
