Result

0.277777777778kWh

kWh = MJ × 0.277777777778

MJ = kWh × 3.6

Example: 10 MJ = 10 × 0.277777777778 = 2.77777777778 kWh.

Express both MJ and kWh in the same base unit J (joule), then cancel the shared base unit.

1
Rewrite MJ in the base unit
$1 MJ = 1, 000, 000 J$
2
Rewrite kWh in the base unit
$1 kWh = 3, 600, 000 J$
3
Forward conversion
$1 MJ = \frac{1 , 000 , 000 J}{3 , 600 , 000 J} \times 1 kWh = \frac{1 , 000 , 000}{3 , 600 , 000} kWh = 0.277777777778 kWh$
4
Reverse conversion
$1 kWh = \frac{3 , 600 , 000 J}{1 , 000 , 000 J} \times 1 MJ = \frac{3 , 600 , 000}{1 , 000 , 000} MJ = 3.6 MJ$
