Formula
1 m² = 10 000 cm² = 1 000 000 mm² = 1e-6 km² = 10,7639 ft² = 1 550 in² = 1,19599 yd² = 0,000247 ac = 0,0001 ha
About this calculator
The Area Converter is a tool that converts area values between major units, including square meters (m²), square centimeters (cm²), square millimeters (mm²), square kilometers (km²), square feet (ft²), square inches (in²), square yards (yd²), acres, and hectares. It works using fixed conversion factors: for instance, 1 m² equals 10,000 cm², 1,000,000 mm², 0.000001 km², 10.7639 ft², 1,550 in², 1.19599 yd², 0.000247 acres, and 0.0001 hectares. Simply input the value and select the source and target units to get the result instantly.
This calculator is useful in many practical scenarios, such as calculating land areas, real estate, construction materials (flooring, tiles), architecture and engineering projects, or agricultural and scientific conversions. For example, when buying a plot in hectares and needing to compare with a property in square meters, or when estimating the amount of flooring for a room with measurements in different units.
When using the converter, ensure the input values are accurate and note that conversions follow international standards. The tool handles very large or small values using scientific notation automatically. Units like acres and hectares are common in agricultural and urban planning contexts, while m² and ft² are frequent in construction and real estate. Avoid manual rounding, as the tool provides precise results.
Frequently asked questions
How do I convert square meters to square feet?
Multiply the value in m² by 10.7639. For example, 50 m² equals 50 × 10.7639 = 538.195 ft².
What is the difference between a hectare and an acre?
A hectare is a metric unit equal to 10,000 m², while an acre is an imperial unit equal to approximately 4,046.86 m². One hectare is about 2.47 acres.
Can I convert very large areas, like states or countries?
Yes, the tool supports large values using scientific notation. For example, 1,000,000 m² can be converted to 1 km² or 100 hectares.
Does the converter work for both imperial and metric units at the same time?
Yes, you can convert between any combination, such as m² to ft², acres to hectares, or yd² to m². Just select the desired units.
