Physical constants

Example
Units and constants
Unit simplification. For example, a Joule is defined as one
kg*m /s . Thus:
2 2
USIMPLIFY(5_kg*m2/s2) returns 5_J
The values of 34 math and physical constants can be
selected by name and used in calculations. These
constants are grouped into four categories: math,
chemistry, physics and quantum mechanics. A list of all
these constants is given in "List of constants" on page 396.
To display the constants, press
