MetricConversion

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 18(CONV) and then input the two-digit number that corresponds to the command you want.

To convert 5 cm into inches b

A5 18(CONV)

02(cm'in)=

To convert 100 g into ounces b

A100 18(CONV)22(g'oz)=

To convert –31°C into Fahrenheit b

A-31 18(CONV)38(°C'°F)=

E-51
