What is Area?
Area is the measurement of the two-dimensional space enclosed within a shape or surface. It represents how much surface a flat object occupies and is expressed in square units such as square meters (m²), square feet (ft²), acres, and hectares. Area measurement is fundamental in mathematics, engineering, architecture, construction, agriculture, real estate, land surveying, and environmental planning.
Different countries and industries use different area units depending on local standards, regulations, and practical requirements. The square meter (m²) is the internationally accepted SI-derived unit of area, while square feet (ft²) are widely used for residential and commercial properties in the United States and several other countries. Larger land areas are commonly measured in hectares, acres, or traditional regional units.
Understanding area units helps you compare property sizes, estimate construction materials, calculate flooring, roofing, painting, and landscaping requirements, and interpret maps, land records, and engineering drawings.

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.
