Heisenberg's Uncertainty Equation always uses "kg" as the mass and "m" as the x value. The speed of light equation c=v(lambda) always uses meters for the wavelength. Ephoton- threshold energy= kinetic energy. This equation uses Joules/photon as the unit of energy and the mass in kilograms for the kinetic energy. The constants on the equation sheet also has units in them too in case you want to check them.
I always like to remind myself of the units for J before doing a calculation because for most, if not all, equations the values you use for mass should be in kilograms, distance should be in meters, and time should be in seconds
