Perform all of these examples in the COMP Mode (N1).
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 recall a metric conversion command, press 18(CONV). This
displays the metric conversion command menu. Input the two-digit
number that corresponds to the metric conversion you want to recall.
See Appendix <#117> for a list of all of the metric conversion
commands and conversion formulas.
•Conversion formula data is based on the “NIST Special Publication
