1 MBtu = 1,000 BTU
1 Therm = 100,000 BTU
1 BTU = 0.293071 Wh
1 watt = 3.41214 BTU/h (or 1 wh is about 3.41214BTU)
1 BTU = 1 055.05585 joules (most people round this off and I've seen it vary a little depending on what source you are looking at)
I think this is what you are looking for. Let us know if you want any clarification.
