UFACTOR

Unit factor conversion. Converts a measurement using a

 

compound unit into a measurement expressed in

 

constituent units. For example, a Coulomb—a measure of

 

electric charge—is a compound unit derived from the SI

 

base units of Ampere and second: 1 C = 1 A * 1 s. Thus:

 

UFACTOR(100_C,1_A)) returns 100_A*s

USIMPLIFY

Unit simplification. For example, a Joule is defined as one

 

kg*m2/s2. Thus:

 

USIMPLIFY(5_kg*m^2/s^2) returns 5_J

Physical constants

The values of 34 math and physical constants can be selected (by name or value) 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 449.

To display the constants, press SFand then tap

.

Example

Suppose you want to know the potential energy of a mass

 

of 5 units according to the equation E = mc2.

 

1.

Enter the mass and

 

 

the multiplication

 

 

operator:
