Area Calculator FAQ
What is the formula for calculating area?
The formula depends on the shape: Square = side², Rectangle = length × width, Circle = π × radius², Triangle = ½ × base × height.
What units can I use for area calculations?
You can input measurements in meters, centimeters, feet, or inches. The area will be calculated in square units (m², cm², ft², in²).
How do I convert between area units?
To convert area units, remember that 1 m² = 10,000 cm², 1 ft² = 144 in², 1 m² ≈ 10.764 ft². Use our unit converter for precise conversions.
What's the difference between perimeter and area?
Perimeter is the distance around the outside of a shape (measured in linear units), while area is the space inside a shape (measured in square units).
