Actually, 1 Mcf (1000 CF) is roughly equal to 1MMBtu (1,000,000 Btu or 1 million Btu). Put another way, there are approx. 1,000 Btu in 1 CF of Natural Gas. A CF of measurement as used in this example is measured at ST&P (standard temperature and pressure) which is 68 deg. F and 14.696 psi absolute pressure (roughly sea level avg. atmospheric pressure).
