Converting Units of Measure

With the TI

-86, you can convert a value measured in one unit into its equivalent value in

another unit of measure. For example, you can convert inches to yards, quarts to liters, or
degrees Fahrenheit to degrees Celsius.

The units of measure from which and to which you convert must be compatible. For
example, you cannot convert inches to degrees Fahrenheit, or yards to calories. Each menu
item on the

CONV

menu (page 62) represents a unit-of-measure group, such as length

(

LNGTH

), volume (

VOL

), and pressure (

PRESS

). Within each menu, all units are compatible.

Converting a Unit of Measure

To use any conversion instruction, the syntax is:
