To insert a constant:

1.Position your cursor where you want the constant inserted.

2.Press žto display the physics constants menu.

3.Press —˜™š(or, you can press žto access the next page, one page at a time) to scroll through the menu until the constant you want is underlined, then press ‘to insert the constant.

Conversion Functions

There are four types of conversions: coordinate (polar/rectangular), angular (degrees/radians), time (decimal/minutes–seconds), and unit (cm/in, °C/°F, l/gal, kg/lb).
