Frequently Asked Questions
Metric Conversion
The calculator's built-in metric conversion commands make it simple to convert values from one unit to another. You can use the metric conversion commands in any calculation mode except for BASE-N and TABLE.
To input a metric conversion command into a calculation, press 
(CONV) and then input the two-digit number that corresponds to the command you want.
Example 1: To convert 5 cm into inches (LineIO)
5
(CONV)

(cm
in)

Example 2: To convert 100 g into ounces (LineIO)
100
(CONV)
(g
oz)

Example 3: To convert -31°C into Fahrenheit (LineIO)

31
(CONV)
(°C
°F)
