- ‘One micron is 1 millionth of a meter, and chips with narrower gaps between transistors can perform more functions faster.’
- ‘Most fluid inclusions are small, only a few microns to tens of microns in diameter, but large inclusions visible to the naked eye are known.’
- ‘Banning carry bags less than 20 microns or five microns doesn't quite matter because these bags are recyclable.’
- ‘The reactors range in diameter from about 400 to 60 microns, or millionths of a meter.’
- ‘Nanowires are crystals only a few nanometers in diameter but up to several microns in length.’
- ‘The bubbles then expand to a much larger size, about 6,000 microns, or millionths of a meter - large enough to be seen with the unaided eye.’
