State the size of red blood cell in micrometers and converts it to millimetres

1 answer

The average diameter of a red blood cell is approximately 6 to 8 micrometers (µm). To convert micrometers to millimeters, you can use the conversion factor that 1 millimeter (mm) is equal to 1000 micrometers (µm).

So, to convert 6 to 8 µm to mm:

  • For 6 µm:
    \( 6 , \text{µm} = \frac{6}{1000} , \text{mm} = 0.006 , \text{mm} \)

  • For 8 µm:
    \( 8 , \text{µm} = \frac{8}{1000} , \text{mm} = 0.008 , \text{mm} \)

Therefore, the size of red blood cells in millimeters is approximately 0.006 to 0.008 mm.
