Obs | From | To | Result | Description |
---|---|---|---|---|
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 |
5 | kg/MWh | tn/TJ | 0.27777777778 | 0.001 tn/kg / 0.0036 TJ/kWh |
6 | kg/MWh | tn/MJ | 0.00000027777777778 | 0.001 tn/kg / 3600 MJ/MWh |
