    Here are the conversion factors for those various expressions of wind speed: 1 m/s = 2.237 statute mile/h = 1.944 knots 1 knot = 1.151 statute mile/h = 0.514 m/s 1 statute mile/h = 0.869 knots = 0.447 m/s. Note: 1 statute mile = 5,280 feet = 1,609 meters

    For example, the conversion of a flowrate of kg/s to kmol/s only requires dividing by the molar mass in g/mol (as = =) without multiplying by 1000 unless the basic SI unit of mol/s were to be used, which would otherwise require the molar mass to be converted to kg/mol.

    For example, a mass flow rate of 1,000 kg/h of air at 1 atmosphere of absolute pressure is 455 SCFM when defined at 32 °F (0 °C) but 481 SCFM when defined at 60 °F (16 °C). Due to the variability of the definition and the consequences of ambiguity, it is best engineering practice to state what standard conditions are used when communicating ...

    Change in volume with increasing ethanol fraction. The molar volume of a substance i is defined as its molar mass divided by its density ρ i 0: , = For an ideal mixture containing N components, the molar volume of the mixture is the weighted sum of the molar volumes of its individual components.

  9. Talk:Molecular mass - Wikipedia

    en.wikipedia.org/wiki/Talk:Molecular_mass

    The unit of quantity is mol (defined as containing Avogadro number molecules), the unit of mass is kg, so the unit of molar mass is kg/mol (for instance 0.01802 kg/mol for water.) The molar mass of any substance can be obtained multiplying the relative molecular mass (often still called molecular weight and abbreviated as MW) by 0.001 kg/mol.
