Discover the ease of energy conversion with our kJ to Wh tool. Newtum's intuitive Kilojoule to Watt-hour Converter simplifies your calculations, sparking curiosity for seamless unit conversion.
A kilojoule is a unit of energy in the International System of Units (SI). It is equivalent to one thousand joules, where a joule is the energy expended (or work done) when applying a force of one newton over a distance of one meter. Kilojoules are commonly used in various scientific and engineering contexts, including nutrition, physics, and energy resource management.
Definition of Watt-hourA watt-hour (Wh) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time. Essentially, it denotes the amount of work done or energy provided over the span of an hour by a system delivering or consuming a constant power of one watt. Watt-hours are a standard unit of energy used by electric utilities for billing purposes.
| Kilojoule (kJ) | Watt-hour (Wh) |
|---|---|
| 1 kJ | 0.2778 Wh |
| 10 kJ | 2.778 Wh |
| 20 kJ | 5.556 Wh |
| 30 kJ | 8.334 Wh |
| 40 kJ | 11.112 Wh |
| 50 kJ | 13.89 Wh |
| 60 kJ | 16.668 Wh |
| 70 kJ | 19.446 Wh |
| 80 kJ | 22.224 Wh |
| 90 kJ | 25.002 Wh |
| 100 kJ | 27.78 Wh |
1 kJ = 0.2778 Wh
1 Wh = 3.6 kJ
Example 1:
Convert 5 kJ to Wh:
5 kJ = 5 × 0.2778 Wh = 1.389 Wh
Example 2:
Convert 10 kJ to Wh:
10 kJ = 10 × 0.2778 Wh = 2.778 Wh
