Below is a quick summary of frequently used units of measure.

Frequently Used Units of Measure
 1 MMBTU =  10 Therms =   1 dekatherm (dth)
 1 MCF =  1000 cubic feet =  1 MMBTU*
 1 BCF =  1 billion cubic feet =   1 million MMBTU*
 1 TCF =  1 trillion cubic feet =  1000 BCF
 1 gigajoule =  0.9478 MMBTU  
 1 Kilowatt-hr =  3412 BTU  
 #2 oil =  139,000 BTU/gal  
 #6 oil =  150,000 BTU/gal  
 Propane =   91,600 BTU/gal  
*Based on natural gas approximate heat value of 1,000 BTU per cubic foot.
