A fire marshal, in the United States and Canada, is often a member of a fire department but may be part of a building department or a separate department altogether.
An average human red blood cell is approximately 5 microns in diameter. The average diameter of human hair is roughly 0.0035 inches in diameter, which is equivalent to 75 microns. The abbreviation micron was initially used to distinguish the units of a tool used to measure small distances, also called a micrometer.
What is the unit of measurement for measuring cells and what is its symbol? Cells are usually measured in microns (1 micron = 0.000001 meters, or 0.001 millimeters). Subcellular structures might be measured in microns or nanometers (1 nanometer (nm) = â¦ 0.000000001 meters).NSWER Generally in Science, you would use the Metric system of measurement. Therefore, when talking about cells and microscopic organisms, you would be measuring using MICROMETRE (abbreviated: Âµ --micron) or stated as: Âµm (micro metre).
