E raised to a power with units

In summary, the argument of an exponential must be dimensionless and cannot have any units associated with it. This means that when e is raised to a power with units of mass, there must also be one or more terms with a dimension of M-1 present in order for the calculation to be valid. The unit on the exponent must be unitless in order for the calculation to be accurate.

When e is raised to a power with units of mass what is the units of the resulting solution?

e^{mass}. But more likely, there's a constant missing from your formula.

It can never be done that way. e, or any other constant, can only be raised to a dimensionless quantity. So, if you find a mass term in the exponent, there must also be one or more terms together having a dimension of M-1, and vice versa.

In dimensional analysis, the argument of an exponential must be dimensionless. In other words the argument of an exponential cannot have any units associated with it.

Edit: I see that I have been beaten to it.

I have simplified the example because the actual formula has e raised to multiple units. I thought if I could understand how a single unit is handled then I could figure out all of the units would be handled in the actual formula.

The unit mass is associated with a numerical value so e^mass can be computed. I just don’t understand what the units would be after the calculation.

What, praty tell, is the unit on the exponent (in its entirety)?

I have been working in kg, Js, and meter, seconds. I think I can change kg into eV and then into Js and perhaps I can arrive at a unitless exponent.

Thanks for the guidance.
