What is the meaning for the unit kilogram-mole?

7,048

The mole is defined as the number of atoms in 12 g of ${}^{12}\mathrm{C}$.

Some people also call this the gram-mole (g-mole), i.e. 1 mole = 1 g-mole. The kg-mole is then defined bt 1 kg-mole = 1000 g-mole = 1000 mole, so it is the number of atoms in 12 kg of ${}^{12}\mathrm{C}$.

If you really want to confuse people you could also use lb-mole...

    Recently, I came across the unit J/(kg-mole * K). What is the meaning of kg-mole? Please explain me the meaning behind it.

    Thanks in advance,

      Can you quote the place where you found this unit, with some context?

    In the world of chemical engineers in industry, they are only interested in getting the chemical ratios of mixtures correct, so U.S. engineers typically do use the lb-mole.

    U.S. units confuse everybody, including some U.S. engineers.
