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).
