## How to convert

1 decimeter (dm) = 100 millimeter (mm). Decimeter (dm) is a unit of Length used in Metric system. Millimeter (mm) is a unit of Length used in Metric system.

## Decimeter: A Unit of Length

The decimeter (dm) is a unit of length in the metric system, which is the most widely used system of measurement in the world. The decimeter is equal to one tenth of a meter, which is the SI base unit of length. The decimeter is also a derived unit in the International System of Units (SI), which is the official system of measurement for science and engineering. The symbol for decimeter is dm. The decimeter is used for measuring medium distances and dimensions, such as the height of a bookshelf or the width of a door. The decimeter is also used for measuring volumes, such as the volume of a cube or a box. The decimeter is named after the deci prefix, which means one tenth in Latin. In this article, we will explore the definition, history, usage and conversion of the decimeter as a unit of length.

## How to Convert Decimeter

The decimeter can be converted to other units of length by using conversion factors or formulas. Here are some examples of how to convert decimeters to other units of length in the SI system, the US customary system and other systems:

• To convert decimeters to centimeters, multiply by 10. For example, 10 dm = 10 × 10 = 100 cm.
• To convert decimeters to meters, divide by 10. For example, 10 dm = 10 / 10 = 1 m.
• To convert decimeters to kilometers, divide by 10000. For example, 10 dm = 10 / 10000 = 0.001 km.
• To convert decimeters to inches, multiply by 3.937. For example, 10 dm = 10 × 3.937 = 39.37 in.
• To convert decimeters to feet, multiply by 0.328. For example, 10 dm = 10 × 0.328 = 3.28 ft.
Decimeters also can be marked as decimetres.

## Millimeter: A Unit of Length

A millimeter is a unit of length in the metric system, which is based on the International System of Units (SI). It is defined as one thousandth of a meter, which is the SI base unit of length. One millimeter can be written as 1 mm or 0.001 m.

## How to convert millimeter to other units of length

To convert millimeter to other units of length, we need to use conversion factors that relate the millimeter to the desired unit. For example, to convert millimeter to centimeter, we need to know that 1 cm = 10 mm, so we can divide the number of millimeters by 10 to get the number of centimeters. Similarly, to convert millimeter to inch, we need to know that 1 in = 25.4 mm, so we can divide the number of millimeters by 25.4 to get the number of inches.

Here are some common conversion factors for millimeter and other units of length in the US standard system and the SI system:

• 1 mm = 0.1 cm
• 1 mm = 0.03937 in
• 1 mm = 0.001 m
• 1 mm = 0.000001 km
• 1 mm = 0.00000062137 mi
• 1 mm = 0.00000053996 nmi
Millimeters also can be marked as millimetres.
