How to convert meters to millimeters

The meter is the SI base unit of length, defined by the distance light travels in a vacuum in 1/299,792,458 of a second. Nearly every other length unit is now legally defined against it.
The millimeter is one thousandth of a meter and the workhorse of precision measurement — engineering drawings, 3D printing tolerances and rainfall totals are all quoted in millimeters.
