Are US units correct?

Only this:

CONVERT(1_km,1_)
"Error: Inconsistent units"

My guess is that it strips the inch part from the input before trying to convert and gets really confused as the "in" is a reserved word in CAS based on a previous post here.

I sure would like a working conversion/units/prefix part and if we have to skip the "in" and use "inch" everywhere thats fine with me.

On the physical calculator, in CAS mode, typing

Code:

CONVERT(1_(km),1_(inch))

gives "Error: Inconsistent units".

But typing

Code:

convert(1_(km),1_(inch))

works, except that "_inch" is displayed as "_" at the end of the numerical answer. Also, lowercase "convert" is displayed as uppercase CONVERT.

However, copying this command back into the entry line gives

Code:

convert(1_(km),1_(inch))

which is correct.

Using the "Sto->" key like this:

Code:

1_(m)->_inch

also works, although once again "_inch" is displayed as "_" in the result.

However,

Code:

1_(m)->1_(inch)

gives an error, which seems inconsistent with the behaviour of "convert".

The only definite bug that I have found is the non-display of "inch". However, I feel that the system could be more forgiving of variant input than in fact it is.
