How to convert Nm3 to m3

The nominal volume refers to the volume under standard conditions (i.e., standard pressure and standard temperature). The conversion related to volume involves converting it in response to changes in temperature and pressure. The formula is pv/t = p1*v1/t1, where p is the standard pressure, t is the standard temperature, v is the volume, v1 is the volume under the changed conditions, and p1*v1 represents the temperature and pressure after the changes.

pv/t = p1*v1/t1; p is the standard pressure, t is the standard temperature, v is the volume, v1 is the volume under the changed conditions; p1*v1 represents the temperature and pressure after the changes.

Dividing the specific gravity by 22.4 gives kilomoles, and multiplying that by the molecular weight (or average molecular weight) yields kilograms. The standard volume is the volume at 1 atmosphere of pressure (absolute pressure) and 0 degrees Celsius (273 K). The pressure, temperature, and volume under standard conditions are commonly denoted as P0, T0, and V0, while those under actual conditions are simply referred to as P, T, and V. Since P0=1 and T0=273, according to the formula P0V0/T0=PV/T, it follows that V0=273PV/T. Here, P is the actual pressure of the gas (absolute pressure), T is 273+t, where t is the actual temperature of the gas in degrees Celsius, and V represents the actual volume of the gas in m3. The resulting V0 is Nm3. The same V=V0*T/(273*P)
