Physical constants in the calculator, Unit conversions | HP 49g

These operations produce the following output:

Unit conversions

The UNITS menu contains a TOOLS sub-menu, which provides the following functions:

CONVERT(x,y): convert unit object x to units of object y

UBASE(x):	convert unit object x to SI units
UVAL(x):	extract the value from unit object x
UFACT(x,y):	factors a unit y from unit object x
UNIT(x,y):	combines value of x with units of y

Examples of function CONVERT are shown below. Examples of the other UNIT/TOOLS functions are available in Chapter 3 of the calculator’s user’s guide.

For example, to convert 33 watts to btu’s use either of the following entries:

CONVERT(33_W,1_hp) `

CONVERT(33_W,11_hp) `

Physical constants in the calculator

The calculator’s physical constants are contained in a constants library activated with the command CONLIB. To launch this command you could simply type it in the stack: ~~conlib`, or, you can select the command CONLIB from the command catalog, as follows: First, launch the catalog by using: ‚N~c. Next, use the up and down arrow

keys —˜to select CONLIB. Finally, press the F(@@OK@@) soft menu key. Press `, if needed. Use the up and down arrow keys (—˜) to navigate through the list of constants in your calculator.
