Unit Conversion; Physics Constants - Citizen SR-281N Instruction Manual

Unit Conversion

The calculator has a built-in unit conversion feature that enables you to
convert numbers among different units.
1. Enter the number you want to convert.
2. Press [ CONV ] to display the menu. There are 7 menus, covering
distance, area, temperature, capacity, weight, energy, and
pressure.
3. Use the [ CONV ] to scroll through the list of units until a
appropriate units menu is shown, then [=].
4. Pressing [ ] or [ 2nd ] [ ] can convert the number to
another unit.
