**There are 10 decimeters in 1 meter, which is a measurement in the metric system.** "Dec" is the Latin root that means "ten."

The metric system includes a number of specific units that each indicate the ratio based on the unit's name, which is often derived from Latin terminology. Because of this, it is often easy to calculate metric distances from unit to unit.

Just as "dec" is Latin for 10, "centi" serves as a prefix for centimeter, which means "hundred." There are 100 centimeters in 1 meter and 10 centimeters in 1 decimeter. Other key prefixes that are part of the metric measurement system include milli, micro, nano and pico.
