. Navigation works as in the other cata-
logs. There is one specialty, however:
(i.e.
) will execute the inverse of the
conversion displayed and leave CONV.
Example: Assume the display set to FIX 3. Then keying in
will display
and 1.619 below telling
you 4 acres equal 1.619 hectares.
Now press
and you will get
9.884 instead, being the amount of
acres equaling 4 hectares.
Press
again and you will see
and 4.000 below confirm-
ing what was just said.
Leave the catalog via
and the display will return to 9.884.
The constant
T
o
may be useful for conversions of temperatures, too; it is found in the
catalog CONST
and
is not repeated here since being only added or subtracted. The
conversion factors or divisors listed below for your information are user transparent in
executing a conversion
– those printed on light green background in this table apply ex-
actly.

For most readers, many of the units appearing in CONV may look obsolete at least. They die hard,
however, in some corners of this world. All these corners have in common is English being spoken
there. For symmetry reasons, we may also add some traditional Indian and Chinese units. Anyway, this
catalog provides the means to convert local to common units.
