Thus, 1 millimeter is equivalent to 1/1000 meter. That implies that a millimeter is the distance that light travels in the vacuum in 1/299792458000 seconds.

Following that, there are 10 millimeters in a centimeter and 100 millimeters in a decimeter. In the other direction, a millimeter is equivalent to 1/10 centimeters. A millimeter is also equivalent to 1000 micrometers.
