UNITS OF SURFACE AREA

__UNITS OF SURFACE AREA -__

**Surface area is a measure of the total area of the outer or exposed parts of a three-dimensional object. Just like with volume, the units of surface area can vary depending on the system of measurement used. Here are some common units of surface area in both the metric system and the imperial system:**

__Metric System:-__

__Square Meter (m²):-__The base unit of surface area in the metric system. It is the area of a square with sides that are 1 meter long.__Square Centimeter (cm²):-__A smaller unit used for measuring smaller areas. One square meter is equal to 10,000 square centimeters (1 m² = 10,000 cm²).

__Imperial System (United States customary system):-__

__Square Foot (ft²):-__The base unit of surface area in the imperial system. It is the area of a square with sides that are 1 foot long.__Square Inch (in²):-__A smaller unit used for measuring smaller areas. One square foot is equal to 144 square inches (1 ft² = 144 in²).

__Other Units:-__

__Acre (ac):-__A unit of area commonly used in agriculture and land measurement. One acre is equal to 43,560 square feet (1 ac = 43,560 ft²) in the U.S. customary system.__Hectare (ha):-__Used for measuring larger areas, especially in agriculture and land measurement. One hectare is equal to 10,000 square meters (1 ha = 10,000 m²).

**It's important to choose the appropriate unit for measuring surface area based on the size and context of the object or area being measured. There are also specialized units for specific applications and industries, but the units mentioned here are the most common and widely used.**
