micrometer

(noun)

An SI/MKS unit of measure, the length of one one-millionth of a meter. Symbols: µm, um, rm

Examples of micrometer in the following topics:

  • 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.
  • 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.
  • Filtration

    • A syringe filter with a pore size of 0.22 micrometers, small enough to capture and retain bacterial and fungal cells.
  • Starvation-Induced Fruiting Bodies

    • Migrating towards each other, they aggregate to form fruiting bodies up to 500 micrometers long containing approximately 100,000 bacterial cells.
  • Anthrax

    • Bacillus anthracis is a rod-shaped, Gram-positive, aerobic bacterium about 1 by 9 micrometers in length.
