Correct mathematical notation for Volumetric Heat Capacity

    What is the correct notation for Volumetric Heat Capacity? I see it written both ways (Wiki for example). I'm pretty sure one is more correct but which is it?

    (1) Btu/ft³·°F
    or
    (2) Btu/(ft³·°F)

    Technically the second is more correct.

    That is, we take that Btu/ft³·°F = ##{Btu} \over {ft^3\cdot °F}## while according to the standard mathematical rules it actually says Btu/ft³·°F = ##\frac{Btu}{ft^3}\cdot °F##.
    The second option avoids this possible confusion by using parentheses.

    However when using units it often happens that you neglect this technicality, because you know what the units are supposed to say.
