Conversion between cubic decimeters and cubic meters
Thread Content
How exactly is it converted? I’m really puzzled why it has to be cubic meters on the device – it’s such a difficult unit to convert. I used to convert using P1V1/T1=P2V2/T2. If the unit of V1 is NM3, then what is the unit of V2 after calculation – cubic meters or NM3?

The value of V2 calculated in this way is in cubic meters under the conditions of P2 and T2. The standard cubic meter is a unit of measurement for gas flow rates; it is often referred to as a mass-like unit because although it appears to be a volume unit, it is actually a mass unit. It is independent of the pressure and temperature at the location where it is used, and therefore it is commonly employed in the chemical industry to calculate the amount in moles or mass of gases involved in chemical reactions.
The pressure here should be absolute pressure; the ‘n’ in nm3 likely refers to standard conditions, and it doesn’t merely denote a unit
The Boyle’s law is applied here; if one of the operating conditions is at standard pressure and temperature (i.e., 101.325 kPa and 273 K), then P/V/T2 represents the corresponding pressure, volume, and temperature for those operating conditions.
The PV=nRT equation applies provided it is in a gaseous state
