Gah, I can remember 0.08206 (R), 4.184 (specific heat of water, and either joules to calories or the other way around), 2.178×10^-18 (some number for figuring out what level n an electron is at), 6.022×10^23 (atoms per mole), 6.626×10^-34 (Planck’s constant) … some others, but I couldn’t remember a little while ago if it’s one inch to 2.45 cm or 2.54 cm. O_o 54! FIVE-FOUR!
I actually put in 1.08206 instead of 1.0825 for tax. *sweatdrop*
Curse you, chemistry! *shakes fist*
