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
00050017(CONV) and then input the two-digit number that corresponds to
the command you want.
To convert 5 cm into inches
