Wh to J Converter - Watt-hour to Joule

Watt-hour (Wh) to Joule (J)

Direct answer

1 Wh = 3,600 J

J = Wh × 3,600

Converter

Input

Result

3,600J

J = Wh × 3,600

Wh = J × 0.000277777778

Example: 10 Wh = 10 × 3,600 = 36,000 J.

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

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