Cells are generally measured in micrometres (μm) or nanometres (nm).

#### Explanation:

1 millimetre is 1,000 micrometres.
1 micrometre is 1,000 nanometres.

Both micrometres and nanometres are used commonly by scientists to measure cells and their components.

Nanometers $\left(n m\right)$ and micrometers $\left(\mu m\right)$

#### Explanation:

Since cells are extremely small to see, it would be absurd to measure them with meters $\left(m\right)$ and kilometers $\left(m m\right)$. Even with millimeters $\left(m m\right)$ you would get large numbers!

So, scientists would commonly use nanometers $\left(n m\right)$ and micrometers $\left(\mu m\right)$.

For conversions:

$1 \setminus n m = 1 \cdot {10}^{-} 9 \setminus m$

$1 \setminus \mu m = 1 \cdot {10}^{-} 6 \setminus m$

I hope that helps!
