Calculations Using Physical Constants
Recall a constant by pressing @ c followed by the number of the
physical constant designated by a 2-digit number.
The recalled constant appears in the display mode selected with the
designated number of decimal places.
Physical constants can be recalled in the NORMAL mode (when not set to
binary, pental, octal, or hexadecimal), STAT mode, PROG mode and EQN
mode.

Note: Physical constants are based either on the 2002 CODATA recom-
mended values, or the 1995 Edition of the ‘Guide for the Use of the
International System of Units (SI)’ released by NIST (National Institute
of Standards and Technology), or on ISO specifications.
