History

The centimeter and decimeter both come from the metric system, which is based on powers of ten.
A centimeter is one-hundredth of a meter, and a decimeter is one-tenth. When converting areas, both sides of the unit are squared, giving:

1 dm² = 100 cm²
So, to go from cm² to dm², we divide by 100.

Common Usage

  • Square centimeters (cm²) are used in school geometry, packaging, and design.
  • Square decimeters (dm²) are used in interior design, tile calculations, and printing.

For example, a tile of 400 cm² has an area of 4 dm².

Conversion Formula

To convert square centimeters to square decimeters:

dm² = cm² ÷ 100

Example:

Convert 500 cm² to dm².

500 ÷ 100 = 5 dm²

So, 500 square centimeters equal 5 square decimeters.
