I use the analysis tool to get a volume measurement but there’s nothing for liquid options in the drop down.
Hi @JKayten,
you would need to make the conversion from the current unit system to the ounces yourself which is scriptable probably. Do you work with regular ounces (oz) or with UK ounces ? The reason for this question is that both are slightly different:
1 cubic centimeter equals 0.03381402 ounces (oz)
1 cubic centimeter equals 0.03519506 ounces (oz) (UK)
Here is a small (windows) program i’ve used for decades: Convert by Josh Madison

Hi -
In Rhino 8, there’s liters.
I’ve added a note to RH-19658 More unit options in Volume please
-wim
I’ve been going to a conversion app online.
It’s rather clunky and I’m not certain I’m doing things correctly.
I’m on the Mac (sorry) so I’m wondering if there’s a units setting that would work. I’m not at all clever with python
Wim!
I note this issue was raised 10 years ago. Is it such a coding task it’s been left undone?
No problem 
Until more volume unit options are build into Rhino i would suggest you just stick with the _-Volume command, choose what ever you like as starting unit system and compute the volume with something reasonable eg. ouput it will be:
Volume = 1000.0 (+/- 1e-07) cubic centimeters
Once you have this, go to the site and choose the the same unit system on the left and see if it matches what you expect eg.
that seems to match my expectation.
I guess it’s not a challenge just a lot of typing and making the decision which of these units make sense for casual users. Do you need exaliter or hogshead at all ?

No need to for a specific website for conversions - just type into google something like “4.3 cubic centimeters in ounces” and it will tell you.
Nice!
