Conversion formula
Centimeter to Decimeter formula: value in dm = value in cm × 0.1.
Decimeter to Centimeter formula: value in cm = value in dm × 10.
How to convert Centimeter to Decimeter
To convert Centimeter to Decimeter, multiply the value in cm by 0.1. This gives the result in dm.
For example, 1 cm = 0.1 dm and 10 cm = 1 dm.
What is Centimeter?
Centimeter (cm): One hundredth of a metre. It is useful for ruler measurements, book widths and a person’s height; kilometres would be impractical for these small dimensions. 1 cm = 10 mm = 0.01 m.
What is Decimeter?
Decimeter (dm): One tenth of a metre. It bridges centimetres and metres in school measurements and appears in volume calculations using cubic decimetres. 1 dm = 10 cm = 0.1 m.
