How to make note with equation?

TS 2008-07-17

Hello.

I want to put note with volume to drawing.

But i want to have note for example like this:

1 m3
1000000 cm3
61027 in3
227 US gal

The same but in different units.

I made note with text:
"SW-Volume@Part1.SLDPRT"

And it shows me in cm3.
Its possible to make equation in note?
