Give the multiplicative constant for the kinetic, potential, thermal, and magical energy terms of the equation:
E(total) = E(kinetic) + E(potential) + E(thermal) + E(magical)
such that E(total) has units of Joules. Assume that kinetic energy = 1/2mv^2, potential energy = mgh, thermal energy = number, magical energy = ObamaCoef*volume*pressure.
KE: parsecs, lbm, shake
PE: smoot, milligrams, jiffy
TE: BTU
ME: torr, cubic fathoms
