"Inches and cubic feet. Liters to cubic feet is somewhere in the realm of 28 liters per cubic foot, so each sub is seeing a little over a cubic foot net. The reccommended ported box size says 30 L, so I'm assuming about 1.1 cubes per sub.
If you can give me some maximum dimensions for the box, I can work on a box design for you. Either cm or inches will work. I'll have to convert it to inches to do the measurements/calculations, but I can convert it back when I'm done. "
30 L = 1830.712 in³
Her is a tabel:

One inch (in) is 2.54 centimeters (cm).
One cubic inch (in3) is 16.387064 cubic centimeters (cm3).
One liter (l) is 1,000 cm3.
1 in3 = 0.016387064 l
or (1,000 : 16.387064) ==>> 1 liter = aprox 61 in3
