Just for meters, and probably for others. What do you have in mind with that, Valery? Which physical significance is, as LucMeekes ask?

Best regards.

Simply because it treats m as an undefined symbol. I can do the same in Mathcad 11:

Please give a physical or mathematical example where it is necessary to have an exponent that carries a unit (is not unitless).

Sorry, later!

I must now go...

Units^Units = Nonsense = No Physical Sense.

Exponents have to be unitless, like the argument of a logarithm function, e.g.

So Mathcad 11 and also Mathcad 15 and even Prime are right. Primes error message is less meaningful, though.

If you chase down thru and find Val's sheet, there's a cute little expression near the top

m := 1

He's not raising units to units, he's raising 1 to the first power.

Yes, I noticed that. But he seems to insist that unit^unit should make sense in a math or physical way.
