Scientific Constants
(fx-991WA)
• A total of 40 commonly-used scientific constants, such
as the speed of light in a vacuum and Planck's constant
are built-in for quick and easy lookup whenever you need
them.
• Simply input the number that corresponds to the scien-
tific constant you want to look up and it appears instantly
on the display.
• See the Scientific Constant Table shown below for a com-
plete list of available constants.
