9.1 CONVERSION OF NUMERICAL VALUES
PG7000 performs all internal calculations in SI units. Numerical values input or output in other units are
converted to SI immediately after entry and back to other units just before output as needed.
The tables below provide the conversion coefficients used by PG7000 to convert numerical values
expressed in SI units to corresponding values expressed in other units.
