Micrometer (MY-kroh-MEE-tur) One micrometer is one millionth (10-6) of a meter or one thousandth of a millimeter. The micrometer is frequently used to measure cells and organelles.
1 micrometer (µm) = 1/1,000,000 meter = 1/10,000 cm
1 nanometer (nm) = 1/1,000,000,000 meter = 1/10,000,000 cm ...
Axons and dendrites in the central nervous system are typically only about one micrometer thick, while some in the peripheral nervous system are much thicker.
Mitochondria are generally oblong organelles, which range in size between 1 and 10 micrometers in length, and occur in numbers that directly correlate with the cell's level of metabolic activity.
5 micrometer) rod-shaped bacterium was grown with the ciliate predator Cyclidium. Medium transfers occurred every seventh day. After 8 to 10 transfers long bacterial cells (up to 20 micrometers) appeared in cultures which had the ciliate.
The Greek letter micron (µ) is applied to small measurements (thoud\sandths of a millimeter), producing the micrometer (symbolized as µm). Measurements in microscopy are usually expressed in the metric system.

In 24 hours the ears of the allergic mice become swollen in much the same way yours (or at least mine!) would if you had rubbed a leaf of poison ivy on them. The amount of swelling is measured with a micrometer (images courtesy of Dr. Moorhead).
We have obtained resolution that results in accurate base calling to greater than 500 DNA bases per channel (200 micrometer deep by 1 mm wide by 25 cm long microchannels filled with 6% PAG).
