Listed here is information which you may find useful in problem-solving. You should note that most problems will be done in terms of SI or Systeme Internationale units. These are the standard units of length, time, mass, etc. that the scientific world has agreed upon for use in publications and research.
A comprehensive listing of physical constants is available via an Internet site which lists many fundamental physical constants.
There are also directories for chemistry information and a server which gives you conversions between units.
For general information on constants (mathematical, physical, chemical, and otherwise), including the infamous googolplex and 5000 digits of Pi, consult problems in physics at U.C. Berkeley's Instructional Technology Program's Web site.
1 atmosphere of pressure = 760 mm Hg = 760 torr = 1.103 x 10^5 Pascals (Pa)
1 mole = 6.022 x 10² ³ particles
R = 0.0821 (L atm)/(mole-K)
2.54 centimeters (cm) = 1 inch
100 cm = 1 meter (m)
1 cubic centimeter (cm³ ) = 10¯ ³ Liter (one milliliter (mL))
1000 milliliters (mL) = 1 Liter (L)
