1)Define the constant mathematically, i.e. show how to equate Newtons to pound-force or psi to Pascals using the constant

2)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.
