How many decimeters are in 1 meter?

One meter contains exactly 10 decimeters. This is by definition of the metric prefix 'deci' (1/10).

How do I convert meters to decimeters?

Multiply by 10 or move the decimal point one place right. For example, 2.5 m = 25 dm.

Why is the decimeter rarely used?

The centimeter is better for small measurements (body, objects) and the meter for larger ones (rooms, distances). The decimeter falls awkwardly between them. But its cube (1 dm3 = 1 liter) is universally used.

Non-Frequently Asked Questions About Meters to Decimeters

Questions nobody should ask - but someone did.

Yes. The centimeter gets all the ruler markings. The meter gets all the race distances. The decimeter sits in the middle, ignored by everyone except the liter (its cubic form). 'It is always cm, cm, cm!' the decimeter might say. But at least it defines the most popular volume unit on Earth.
Barely. Saying 'I am 17.5 decimeters tall' would confuse most people. Saying 'my desk is 12 decimeters long' would cause a pause. But saying '1 decimeter cubed of milk' (1 liter) - everyone gets that. The decimeter hides inside the liter like a successful pen name.
French schools call a 20 cm ruler a 'double decimetre.' This is one of the only contexts where the decimeter is named explicitly. French education keeps the decimeter alive through sheer stubbornness. Every other country just says '20 cm ruler.'
