Summary
What does the unit of a constant mean?
We say the unit of gravitational costant is m3/kg.s2, but what does it mean? I mean, I think we define units when we need to measure a quantity and thereby compare it with other same kind of quantities. So what does it mean to define a unit for a constant, when it doesn't change?

You can use different units, but then the numerical value of the constant also changes. You need to know the units, in order to use the numerical value correctly.

The dimensionality of a constant is chosen based on the equation for which the constant is defined.
