expression1

from one unit to another. Valid

temperature units are:

_

¡C

Celsius

_

¡F

Fahrenheit

_

¡K

Kelvin

_

¡R

For example, 100_

¡C converts to 212_¡F:

To convert a temperature range, use

between two temperature values) specified
by

expression1

from one unit to another. Valid

temperature units are:

_

¡C

For example, a 100_

¡C range (from 0_¡C to

100_

¡C) is equivalent to a 180_¡F range:
