Unit objects
The Units application contains a catalog of 127 imits that you can combine
with real numbers to create unit objects. It also provides you with tools to
manipulate unit objects.
The Units application enables you to:
• convert imits—for example, you can convert the imit object 10_ft to
120Jn or 3.048„m
• factor imits—for example, you can factor 20_W with respect to 1__N
and return 20_N*m/s
• calculate with units—for example, you can add 10_ft/s to 10_mph and
return 16.82_mph.
Overview of the Units application
The calculator’s units are based on tire 7 base units of the International
System of Units (SI): m (meter), kg (kilogram), s (second), A (ampere), K
(kelvin), cd (candela), and mol (mole). The HP 49G makes use of two
additional base units: r (radian) and sr (steradian). The remaining 118
units are compoimd imits, that is, imits derived from the 9 base imits.
For example, in (inch) is defined as .0254m, and Fdy (Faraday) is defined
as 96487 A*s. (See appendix B of the User’s Guide for a complete listing of
the built-in imits and their SI values.)
Units are grouped into the following categories:
length area
volume time
speed mass force energy
power pressure
temperature electric current
angle light radium viscosity
These categories can be chosen from the Units menu (displayed by
pressing (r
