Cura estimates meters and grams necessary for a print. How do I convert that into cm3?

I don’t use cura so I’m assuming you mean length of filament when you say “meters”, in which case calculating the volume (cm3) should be pretty easy.
I assume radius in the formula is half the diameter of the filament, so 1.75/2 on my case? Thank you. That helps immensely .
Exactly. Also, remember to convert millimeters & meters to cm before plugging them in so you end up with cm3 at the end.

If you don’t want to do the math, there is another easy way to get the volume. Once you have saved the g-code, open it using any text editor. The 3rd line from the top will be “MATERIAL: XXXXX”. The X will be replaced by a number, for example, 23879. This number is in cubic millimeters. To get cubic centimeters just divide by 1000 or move the decimal place 3 digits to the left. So for this example, it would 23.879 cm^3.
That WOULD be great, but the 3rd line down on my gcode file is [Filament Used] in meters 
Thank you, though.

Oh that is weird. Just checked though, Cura only puts the volume used in the gcode for the ultimaker machines using UltiGCode. For other machines using RepRap gcode, it gives the value you mentioned. Sorry that didn’t work out for you.
Oh, that’s ok… I don’t mind a little bit of math 
Btw, if you type “cylinder volume” into google a convenient little tool pops up where you can just plug in the numbers. Also, I use slic3r, which gives you the print volume. Slic3r gives you a lot of control but it’s not as user friendly.
