Square Kilometer
A square kilometer (km²) is a large metric unit used to measure wide geographic areas. One km² equals one million square meters, making it perfect for cities, forests, lakes, and regions. It is widely used in maps, environmental studies, and land-use planning.
This scale helps governments, scientists, and researchers describe the size of natural and urban spaces with clarity. Converting km² into acres or square miles provides helpful context across measurement systems.
Square Foot
A square foot (ft²) is a popular area measurement in the US, based on a square with sides one foot long. It is widely used in construction, home layouts, painting coverage, and room dimensions — making it a central unit for homeowners and professionals.
Square feet give a realistic reference for everyday living spaces and material estimates. When comparing internationally, converting to square meters becomes essential.
