micrometers
Tiny distance measurers
Micrometers has two meanings depending on pronunciation.
With stress on the second syllable, it's the plural of micrometer—a precision measuring instrument that uses a calibrated screw to measure small distances with high accuracy: The machinist checked the shaft diameter with micrometers.
With stress on the first syllable, it's the plural of micrometer meaning one millionth of a meter, a unit for measuring microscopic objects: Human hair is typically 50 to 100 micrometers thick.
