Morphology

micromillimeter = millimeter (transparent) = micro + milli + meter

The word is a straightforward prefixation of 'millimeter', with 'micro-' indicating a further thousandfold reduction in size.

Etymology

Micromillimeter combines micro- meaning 'very small', as in microscope, with millimeter, where milli- means 'one-thousandth' and meter means 'measure'. So a micromillimeter is a tiny part of a millimeter — one billionth of a meter — and the name helps you remember it is used for extremely small distances.
