Question #dc627

Answer 1

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.

Answer 2

Nanometers `(nm)` and micrometers `(mum)`

Explanation:

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

So, scientists would commonly use nanometers `(nm)` and micrometers `(mum)`.

For conversions:

`1 \ nm = 1*10^-9 \ m`

`1 \ mum = 1*10^-6 \ m`

I hope that helps!
