## Metric Area Units

In the metric system, area is typically measured in square meters and its derived units. Here are some of the metric units used for measuring area:

**Square millimeters (mm²):**One square millimeter is the area of a square with 1 millimeter sides.**Square centimeters (cm²):**One square centimeter is the area of a square with 1 centimeter sides.**Square meters (m²):**The base unit of area in the metric system; one square meter is the area of a square with 1 meter sides.- S
**quare kilometers (km²)**: One square kilometer is the area of a square with 1 kilometer sides. This unit is often used to measure the area of cities or countries. **Hectares (ha)**: One hectare is equivalent to 10,000 square meters or 0.01 square kilometers. It's commonly used in agriculture and forestry to describe the size of land plots.

## Imperial Area Units

In the Imperial system, commonly used units for measuring area include:

**Square inches (sq in or in²)**: Used for measuring small areas, such as the area of a piece of paper or a computer screen.**Square feet (sq ft or ft²)**: Commonly used for measuring medium-sized areas, such as the floor space of a room.**Square yards (sq yd or yd²)**: Used for larger areas such as the size of a carpet or a small garden.**Acres**: Used for measuring very large areas, such as land for farming or plots of land for building. One acre is equivalent to 43,560 square feet or 4,840 square yards.**Square miles (sq mi or mi²)**: Used for measuring extremely large areas, such as the size of cities or countries.
