Direct answer

1 kJ = 0.000277777778 kWh

kWh = kJ × 0.000277777778

Converter

Input

Result

0.000277777778kWh

kWh = kJ × 0.000277777778

kJ = kWh × 3,600

Example: 10 kJ = 10 × 0.000277777778 = 0.002777777778 kWh.

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

1
Rewrite kJ in the base unit
$1 kJ = 1, 000 J$
2
Rewrite kWh in the base unit
$1 kWh = 3, 600, 000 J$
3
Forward conversion
$1 kJ = \frac{1 , 000 J}{3 , 600 , 000 J} \times 1 kWh = \frac{1 , 000}{3 , 600 , 000} kWh = 0.000277777778 kWh$
4
Reverse conversion
$1 kWh = \frac{3 , 600 , 000 J}{1 , 000 J} \times 1 kJ = \frac{3 , 600 , 000}{1 , 000} kJ = 3, 600 kJ$
