Sorry all, coming to this late.
pV=nRT is a longish wave length Clupea Harengus
Watch V - its m3

Units of pressure?
Try N/m2 or Pa or kPa or mmHg or inches / feet of water or Bar or mBar or Atmospheres or psi etc ad nauseum
We use kPa mostly where 1 Bar/Atmosphere = 101.3 kPa
Mods will decide if this adds anything!
