Nernst Equation Units

[Bailey Giovanoli 1L]

In one of the sapling problems for week 7 and 8, we had to use the Nernst equation. However, we were given partial pressure for the products and molarity/concentration for the reactant. You got the problem correct if you left the units as is and plugged the numbers in. Why is it that you can use partial pressures and concentrations in the equilibrium constant/ reaction quotient for the Nernst equation?

Basically, the units aren't a huge deal here because in the problem everything was in standard conditions and both concentration and pressure are in reference to standard conditions, one bar/atm and molarity can be used for K or Q.
