What is Area Conversion?

Area conversion involves converting measurements of two-dimensional space from one unit to another. Area is measured in square units (like square meters or square feet) because it represents length multiplied by width. Understanding area conversions is essential for real estate, construction, agriculture, interior design, and land management. Different regions use different units - metric areas (square meters, hectares) are standard internationally, while imperial units (square feet, acres) are common in the US and UK real estate markets.
