Area is the measurement of the two-dimensional space enclosed within a shape or surface. It describes how much space a flat object covers and is expressed in square units, such as square meters (m²), square feet (ft²), acres, or hectares. Area is one of the most common measurements used in mathematics, engineering, construction, agriculture, real estate, and land surveying.

Different regions and industries use different area units depending on local standards and practical needs. For example, square meters are the standard SI unit used in most countries, while square feet are commonly used for buildings and property in the United States and several other regions. Larger land areas are often measured in acres, hectares, or traditional local units.

Understanding area units makes it easier to compare property sizes, estimate construction materials, calculate flooring or paint requirements, and interpret maps or land records.

What is Decimal?

Decimal is a traditional unit of land area widely used in Bangladesh, West Bengal, Bihar, Jharkhand, Assam, and other parts of the Indian subcontinent. It is one of the most common units used for measuring residential plots, agricultural land, and small real estate parcels. A Decimal represents exactly one-hundredth (1/100) of an Acre, making it a practical unit for describing small and medium-sized properties.

One Decimal is equal to 435.6 square feet, 40.4686 square meters, 48.4 square yards, and 0.01 Acre. In Bangladesh and many Bengali-speaking regions, Decimal is often referred to as Satak, Shotok, or Shotangsho. Because these names represent the same area measurement, 1 Decimal is exactly equal to 1 Satak.

Decimal remains widely used in land registration documents, property advertisements, mutation records, survey reports, and real estate transactions. For example, a 5-Decimal residential plot and a 5-Satak residential plot describe the same piece of land. This interchangeable use of the two terms is one of the reasons why Decimal continues to be an important unit in local property markets.

Although modern land surveys increasingly use Square Meter and Hectare, Decimal remains deeply rooted in traditional land measurement systems. Property buyers, sellers, surveyors, and real estate professionals frequently use Decimal when discussing plot sizes because it is easy to understand and closely aligned with local land records.

A square meter (m², m^2, sqm, sq mtr, sq meter, sq meter, sq m) is the standard unit of area in the metric system. It measures a square with sides of one meter each. Square meters appear in construction specifications, architectural plans, property deeds in metric-adopting countries, agricultural surveys, and environmental assessments. The unit is mandated by most governments for official land records and international property documentation. Square meters are used worldwide as the standard for property valuation and contract writing. In India, square meters are the official measurement for title deeds, government land registrations, and municipal property taxes.
