What is a Square Centimeter?
A square centimeter (symbol: cm²) is a unit of area in the metric system. It is the area of a square with sides that are one centimeter long. It is a derived unit, based on the meter, which is the SI base unit for length.
The square centimeter is used for measuring small areas, such as in technical drawings, medical imaging (e.g., skin lesions), and for specifying the size of small objects. Our area conversion tool helps you easily convert between square centimeters and other units. For example, 1 square inch is equal to approximately 6.45 square centimeters.
What is the SI unit of Area?
The SI unit of area is the square meter (m²). All other metric area units are derived from the square meter. The square centimeter is directly related to the square meter:
- 1 square meter (m²) = 10,000 square centimeters (cm²)
- 1 square centimeter (cm²) = 0.0001 square meters (m²)
What are Square Centimeters Used For?
Square centimeters are used in various fields where precise measurement of small areas is required:
Science & Medicine
Measuring the area of biological samples, skin conditions, or cross-sections in imaging.
Engineering & Design
Specifying the surface area of small components, in technical drawings, and product design.
Photography
Describing the size of film negatives or digital sensors (e.g., a 35mm film frame is 24mm x 36mm, which is 8.64 cm²).
Everyday Life
Measuring the area of small household items, like a postage stamp or a credit card.
Frequently Asked Questions
Why is the square meter the SI unit of area?
The square meter (m²) is the SI unit for area because it is derived from the base SI unit of length, the meter. This direct relationship ensures a coherent and standardized system of measurement used globally in science and engineering.
How do I convert square centimeters to other area units?
Use our conversion tool above or multiply by the correct conversion factor. For example, to convert cm² to m², multiply by 0.0001. To convert cm² to in², multiply by approximately 0.155.
What's the difference between a centimeter and a square centimeter?
A centimeter (cm) is a unit of length, used to measure distance in one dimension. A square centimeter (cm²) is a unit of area, used to measure a two-dimensional surface. You cannot convert between them.
Is cm² the same as cm^2?
Yes, "cm²" and "cm^2" represent the same unit: square centimeters. The superscript "²" is the standard symbol, while "^2" is a common way to type it when superscript is not available.
