If a red blood cell is 7 x m in size, it means that such a cell is 7 microns or micrometer in size. The unit that completes the sentence will, thus, be microns or micrometer.
According to international system of measurement:
- m = decimeter
- m = centimeter
- m = millimeter
- m = micrometer or micron
- m = nanometer
Thus, a measurement of 7 x m is the same is 7 micons or 7 micrometer.
