On the speaker measurements page there is this formula:
Vas = Vb((Fb/Fs)^2 - 1)

What unit of measurement is Vb?

Vas will have the same dimensions as Vb.
Use either cubic feet for both or litres for both.

Vb = net volume of the test box.

Yes, but what is the unit of measurement?
Liters?
Cubic inches?
Cubic feet?

Doesn't matter which. If you use cu.ft. for Vb, the result for Vas will also be in cu.ft.. Ditto for liters or cu.in.
