Is cubic meters per hour of fuel gas a unit of mass? What is its relationship with cubic per hour?
It is the cube of the volume at standard conditions
It is not a unit of mass, but a unit of volume
Fuel gas, standard cubic meters per hour — volume flow rate； Is it a unit of mass? ——No ； What is its relationship to cubic hours? — Cubic feet (volume under standard conditions), cubic meters (volume measured actually). The difference lies in the variations between standard conditions and actual conditions. Note: Standard temperature and pressure (STP) refers to the standard conditions of temperature and pressure. Since temperatures and pressures vary in different locations on Earth, and even at the same location they can change over time, standard conditions have been established for ease of analysis: 0 °C (273.15 K) and 101 kPa. These values are close to the freezing point of water at sea level. 1 mole of an ideal gas occupies a volume of 22.413996(39) L at STP (CODATA 2002), which is the standard molar volume. This is a standard established to distinguish from ordinary conditions.
It is about converting the environmental conditions under which it is in use, such as temperature and atmospheric pressure, into volume values under standard conditions.
