what is the proper way of writing 1 square millimeter?

Question

(.001m)^2 or (.001m^2) I think it is the first one but Im not sure. Please look over these equations for me so I can have a sufficiently long question to submit.

$1mm^2=(.001m)^2=10^{-6}m^2$ You are right. – Apr 14 '18 at 01:53 — , Apr 14 '18 at 01:53

"1 square millimeter" is usually written $1\ \mathrm{mm}^2.$ This is the area of a square whose side is $1\ \mathrm{mm}.$

If you want to convert to square meters, $1\ \mathrm{mm}^2 = 10^{-6} \ \mathrm{m}^2.$

I believe the second one is the correct one.

The first one makes it look like you are squaring $.001$ as well

However, the second says $.001$ of a square metre which is a lot bigger than a square of one millimetre. I would read "1 square millimetre" as the area of a square with a side of 1 millimetre; if so then the first is correct. – badjohn Apr 06 '18 at 16:32

$1 mm = 0.001 m$

You can square both sides: $1 mm^2 = 0.000001 m^2$
