Other forms: decimeters
In the metric system, a decimeter is a unit of measurement that's about the same as four inches. You can estimate the width of a decimeter by aligning four U.S. quarters horizontally.
There are ten decimeters in a meter, and the word itself comes from the French deci- and the Latin decimus, "tenth." Each decimeter is one-tenth of a meter, a measurement that's common in many parts of the world although relatively unusual in the U.S. Americans also spell it differently than most metric system-users, who write decimetre.
