[ ] This key is used to find the square
root of a number. You must be
careful when entering dimensioned
values because by definition the
square root of a linear dimension
does not exist; therefore the calcu-
lator will correctly give you an er-
ror if you try to do this.
[Conv] This key, used in conjunction with a
dimension key, converts one dimen-
sioned number to another dimen-
sioned number. The one logistical
limitation is that you must maintain
convention. You cannot convert
from a linear dimension like feet,
for example, to a square or cubic di-
mension. This violates convention.
Additional [Conv] Key Functions:
When used in conjunction with the following
keys, the [Conv] key gives
additional functions.

Finds the square (X
Squared) of a number or
dimension. Again, you must
be careful when working with
dimensions because, for ex-
ample, if you try to square an
already square
you would bring it to the
fourth power, which does not
work on this calculator.
