A decimeter (dm) is a unit of length in the metric system, which is used worldwide for most scientific and everyday measurements. A decimeter equals a tenth of a meter, or in other words, 10 centimeters. The term "decimeter" comes from the Greek word 'deka', which means ten, and the Latin word 'metrum', which means measure.
A decimeter is often used in everyday measurements where a meter is too large and a centimeter is too small. An example of an object about a decimeter long is a large pen or a small notebook.
A centimeter (cm) is another unit of length in the metric system, equivalent to one hundredth of a meter. It is often used to measure smaller lengths, such as the thickness of a book, the width of a mobile phone, or the diameter of a coin. The term "centimeter" comes from the Latin word 'centum', which means hundred, and 'metrum'.
As mentioned earlier, one decimeter equals ten centimeters. This means that if you multiply the number of decimeters by 10, you get the equivalent in centimeters.
1 decimeter = 10 centimeters
Conversely, if you divide the number of centimeters by 10, you get the equivalent in decimeters.
1 centimeter = 0.1 decimeter
For example, a 30-centimeter ruler is also 3 decimeters long, and an object of 2 decimeters is 20 centimeters long. This simple conversion makes it easy to switch between the two units, depending on what is most suitable for the specific measurement.
