If two quantities (e.g. X and Y) have different dimensions (dimensions in the sense of length, mass, or time), could the product XY ever be physically meaningful? Obviously X/Y could be, in something like miles/hour. I'm pretty sure that it is possible to multiply quantities with different dimensions, but is the product ever physically meaningful? I just can't imagine something like foot grams, foot hours, or gram hours ever being physically meaningful.
