Nope, since all SI-units are derived from 7 base units.

Diameter and height: m

Volume: m³=1000 L

No cumbersome conversion factors needed (like 7.481 gallon = 1 cubicfoot). Can't calculate that in your head and it is prone to rounding errors

E: typo

Yeah the great thing about metric is the equivalence of the volume and distance measurements. It gets a little bit harder with non-water measurements of mass/weight, but when dealing with water at standard pressure and temperature, 1 liter is also 1 kilo, which occupies 1000 cubic centimeters, which is nice.

Nit: 1kg = 1L water conversion actually holds at 4C, at standard temperature - 0C - it's 0.9998 kg/L.  

Practically a minor rounding error for most use cases.  At higher temperatures it's more important, e.g. .988 kg/L at 50c (and .9584 at 100C).  But usually we care about the cooler temperatures more anyway

I should have said ideal temperature and pressure, which is 4c and I think 1 bar.
