Using defined constants and conversion factors for mass, length, time and temperature, calculate conversion factors for a) foot-pound force to kilowatt-hours b) gallons (1 gal=231in3) to liters (103 cm3) c)BTU per pound moles to joules per kilogram mole. Try to do this using only Appendix 1 or your conversion sheet from 201

Explain the concepts behind g_c. Define the constant mathematically, i.e. show how to equate Newtons to pound-force or psi to Pascals using the constant g_c.
