### What is a Decimeter?

The **Decimetre** (SI symbol dm) or decimeter (American spelling) is a unit of length in the metric system, equal to one-tenth of a meter. The term “Deci” means one-tenth, and therefore decimetre means one-tenth of a meter.

Since a meter is made up of 100 cm, one-tenth of 100 cm is 10 cm. Thus one decimeter measures 10 cm or 3.937 inches

### What is a Millimeter?

The **Millimetre** (international spelling; SI unit symbol mm) or millimeter (American spelling) is a unit of length in the metric system, equal to one-thousandth of a meter, which is the SI base unit of length. Therefore, there are one thousand millimeters in a meter and ten millimeters in a centimeter.

### How to Convert Decimeter to Millimeters?

To convert Decimeter to Millimeters, simply multiply the Decimeter value by 100.

The formula used to calculate Decimeter to Millimeters -

**d**_{(dm)} = **d**_{(mm)} * 100

The distance *d* in Millimeters (mm) is equal to the distance *d* in Decimeters (dm) multiplied by 100.

### How many Millimeters in a Decimeter

In simple terms, 1 dm is equal to 100 mm.

The formula used is 1*100 = 100(mm)

### How many Decimeters in a Millimeter

1 Millimeter is equal to 0.01 Decimeters. So we can also say that there are 0.01 Decimeters in a Millimeter.
