micrometer

Examples of micrometer in the following topics:

• SI Unit Prefixes

  • Thus a millionth of a meter is a micrometer, not a millimillimeter, and a millionth of a kilogram is a milligram, not a microkilogram.
  • In older usage, a micron (a measurement often encountered in physics and engineering) is the same as a micrometer, 10-6 meters.
  • Another older form of usage, the millimicron, is one thousandth of a micrometer, or 1 thousandth of 10-6 meters, or 10-9 meter, now called a nanometer.

• Units of Measurement for Microbes

  • The units used to describe objects on a microscopic length scale are most commonly the Micrometer (oi) - one millionth of 1 meter and smaller units.
  • Most microbes are around 1 micrometer in size.
  • Animal cells are typically around 10 micrometers in size.

• Microbe Size

  • To put a numerical value on microbial size, most measurements of microbes are done with the unit of measure of micrometer, which is one millionth of a meter (one 2,500th of an inch).
  • These bacteria range in size from 0.2 x 0.5 micrometers to 0.3 x 2.0 micrometers.

• Scanned-Probe Microscopy

  • A scan may cover a distance of over 100 micrometers in the x and y directions and 4 micrometers in the z direction.

• Adherence

  • Fimbriae are fine filaments of protein, just 3–10 nanometers in diameter and up to several micrometers in length.
  • This appendage ranges from 3-10 nanometers in diameter and can be up to several micrometers long.

• Intracellular Pathogens

  • They typically range between 1 and 5 micrometers in length.
  • The typical fungal spore size is 1 to 40 micrometers in length.

• Rickettsial Diseases

  • These bacteria range in size from 0.2 x 0.5 micrometers to 0.3 x 2.0 micrometers.

• Components of Blood

  • Erythrocytes (also called red blood cells) are about seven to eight micrometers in diameter and have a disk shape.
  • Leukocytes (also called white blood cells or WBCs) are usually larger in size (10-14 micrometers in diameter) than red blood cells and they lack hemoglobin but do contain organelles, a nucleus, and nuclear DNA.
  • Thrombocytes (also called platelets) are between one to two micrometers in diameter.

• Air Wedge

  • The air gap between the two glass plates has two unique properties: it is very thin (micrometer scale) and has perfect flatness.

• Nitrospirae and Deferribacter

  • It is a Gram-negative nitrite-oxidizing organism with a helical to vibroid morphology 0.9-2.2 x 0.2-0.4 micrometers in size.
