$$h = \SI{6.626e-34}{\joule\second}$$

or electronvolt-seconds:

$$h = \SI{4.136e-15}{\electronvolt\second}$$

But you probably won’t find it in.... Id: 307

If you look up the value of Planck’s constant, you’ll usually find it in either the SI units, Joule-seconds:

$$h = \SI{6.626e-34}{\joule\second}$$

or electronvolt-seconds:

$$h = \SI{4.136e-15}{\electronvolt\second}$$

But you probably won’t find it in parsec-Tesla-Coulomb-inches:

$$h = \SI{8.45e-49}{pc.T.C.in}$$

or Kelvin-second-(units-of-entropy)-moles

$$h = \SI{2.77e-33}{K.s.ue.mol}$$

or slug-barns per fortnight:

$$h = \SI{0.549}{slug.barn/fortnight}$$

This one is particularly interesting because the numerical value is on the order of 1.

Got a better suggestion? I’d love to see it in the comments!
