## Conversion to other units of length

The measurement of lengths and distances is a fundamental aspect in many scientific and technical fields. Millimeters are a frequently used unit of measurement. In this article, we take a look at how millimetres can be converted into other units.

**1. millimeters to centimeters**

One centimeter (cm) is equal to 10 millimeters.

Conversion formula: mm / 10 = cm

*Example:*

- 20 mm = 2 cm
- 75 mm = 7.5 cm

**2. millimeters to decimeters**

One decimeter (dm) corresponds to 100 millimeters.

Conversion formula: mm / 100 = $dm$

*Example:*

- 200 mm = 2 dm
- 350 mm = 3.5 dm

**3. millimeters in meters**

One meter (m) corresponds to 1,000 millimeters.

Conversion formula: mm / 1.000 = m

*Example:*

- 1,000 mm = 1 m
- 2,500 mm = 2.5 m

**4. millimeters to kilometers**

One kilometer (km) corresponds to 1,000,000 millimeters.

Conversion formula: mm / 1,000,000 = km

*Example:*

- 1,000,000 mm = 1 km
- 5,000,000 mm = 5 km

**5. millimeters in inches**

One inch corresponds to approximately 25.4 millimeters.

Conversion formula: mm / 25.4 = inch (inch)

*Example:*

- 25.4 mm = 1 inch
- 50.8 mm = 2 inches

## Conclusion
