What does Nm3 stand for in gas measurement?

• A. Normal cubic meter at measured conditions
• B. Normal cubic meter at standard temperature and pressure
• C. New cubic meter at standard pressure
• D. Natural cubic meter at standard temperature

Answer: (B)

Nm3 denotes a Normal cubic meter, a gas volume defined at standard conditions so results can be compared regardless of how hot or pressurized the gas was when measured. Standard conditions are typically 0°C and 1 atm (about 273.15 K and 101.325 kPa). Expressing volume at these conditions lets engineers and traders compare gas quantities consistently across different sources. The other options mix up the meaning or omit a required part of the standard definition, such as using measured conditions, inventing a term like “New,” or leaving out the pressure reference. So the correct interpretation is Normal cubic meter at standard temperature and pressure.
