expression_unit2
Converts an expression from one unit to another.
The units must be in the same category.
The _ underscore character designates the units.
For a list of valid pre-defined units, refer to the
module about constants and measurement units.
You can press
2
9
to select units from a
menu, or you can type the unit names directly.
To get the _ underscore when typing units
directly, press
¥ 
Note: The
4
conversion operator does not handle
temperature units. Use
tmpCnv()
and
@ @ @ @ tmpCnv()
instead.

.
This is not the same as calculating 10 raised to
the power of each element. For information about
the calculation method, refer to
cos()
.
squareMatrix1
must be diagonalizable. The result
always contains floating-point numbers.
