For maths and physics, what values are the best to store in the calculator letters? Personally I've stored 1/29something which is the new metre standard but not sure what else to store, does anyone else do this?
DEFINITELY save all your physics constants; Planck's constant, mass of Earth, g, charge on an electron, etc. Saves a crapton of time every time you need to key them in for calculations. Also if you do chemistry spare letters are a great place to chuck values from your stoichiometry calculations so you don't get done for rounding errors later on.
