Vesna [10]

Answer: The length of the cell in millimetres is 0.0015.

Explanation:

Given conversion :

$1000\mu m=1mm$

Thus $1\mu m=\frac{1}{1000}mm=0.001mm$

Given : Length of the cell = 1.5 micrometers $(\mu m)$

To find: Length of the cell in milllimeters (mm)

Length of the cell in milllimeters (mm) = $1.5\times 0.001mm=0.0015mm$

The length of the cell in millimetres is 0.0015.
