For converting angles in any quadrant from one system to another, the following table of conversion factors can be used. FROM degrees radians grads degrees 180 .9 radians 180 200 grads x .9 rr >` 265 These operations can be performed in any angular mode setting of the calculator.

setting
of
the

Because
of
the
independence
of
these
conversions
from
the
angular
mode
of
the
calculator,
you
must
be
extremely
careful
when
using
the
results
for
further
calculations.
The

mode
must
be
adjusted
to
match
the
