Relationship between Millimeters and Decimeters
Millimeters and decimeters are both units of length in the metric system. Understanding the relationship between them can help in converting measurements accurately.

Definition of Millimeter and Decimeter
- A millimeter is a unit of length in the metric system equal to one-thousandth of a meter. It is commonly used for measuring very small distances.
- A decimeter is a unit of length in the metric system equal to one-tenth of a meter. It is larger than a millimeter but smaller than a meter.

Conversion between Millimeters and Decimeters
- Since there are 10 millimeters in a centimeter and 10 centimeters in a decimeter, there are 100 millimeters in a decimeter.
- Therefore, 100 millimeters is equal to 1 decimeter.

Example
- For example, if you have a length of 300 millimeters, you can convert it to decimeters by dividing by 100 (since 100 millimeters = 1 decimeter).
- 300 millimeters / 100 = 3 decimeters.

Conclusion
- Understanding the relationship between millimeters and decimeters can be useful in converting measurements between the two units accurately. Remembering that 100 millimeters is equal to 1 decimeter can simplify the conversion process.
