A decimetre is a unit of length in the metric system, equal to one tenth of a metre, the current SI base unit of length. In simple words there are 10 cm in a decimetre. It can be written in scientific notations as 100×10 m (engineering notation) or 1 E-1 m (exponential notation) — meaning 100 × 1 mm or 1 m / 10 respectively.
