In Calc type
'e T m^2 / hbar
Convert this to SI units with u c si RET
- That's perfect. We get a dimensionless number.
Let's try again. In Calc type (more my range of numbers)
'e T nm^2 / hbar
Now when we type again u c, Calc remembers what we did before.
So as a unit it offers "default 1". Let's take this default.
So just type RET
Error: No units specified
In other words: if an expression with units simplifies to a
dimensionless number, Calc does not accept the unit "1", though it
even offers this unit as a default for calc-convert-units.
