Appendix C

Units

The HP 49G contains a catalog of 127 units that you can use to create unit

objects. A imit object is a real number linked to a unit expression by the

underscore character. For example, 2„in is a unit object representing 2

inches.

The calculator’s imits are based on the 7 base mrits of the International

System of Units: m (meter), kg (kilogram), s (second), A (ampere), K

(keMn), cd (candela), and mol (mole). The HP 49G makes use of two

additional base imits: r (radian) and sr (steradian). The remaining 118

imits are compoimd units, that is, units derived from the 9 base units.

You select a imit by pressing

(n (UNITS),

choosing the appropriate category

from the Units menu—length, area, volume, etc.—and finally selecting the

unit from the category submenu. You do this when creating a unit object

or when converting one unit to another. You can also perform calculations

using unit objects. (See Advanced User’s Guide at

http://www.hp.com/calculators/hp49 for more infonuation.)
