Answer

We need conversion factors, which are listed below, and a code that does the actual conversion.

1	MWh	MJ	3600	1 MWh = 1 MWh * 3600 s/h = 3600 MWs = 3600 MJ
2	toe	MJ	35000	1 toe = 1000 kgoe = 1000 kg * 35 MJ/kg = 35000 MJ
3	mg/MWh	mg/MJ	0.00027777777778	1/3600
4	kg/MWh	kg/GJ	0.27777777778	1/3.6
