About Kilojoule (kJ)

Equal to 1,000 joules, the kilojoule is the standard energy unit on food nutrition labels in Australia, New Zealand, and the European Union. A typical adult's daily energy requirement is about 8,700 kJ (approximately 2,080 kilocalories), and food packages in metric countries display energy content in kJ.

About Watt-hour (Wh)

One watt sustained for one hour equals 3,600 joules. The watt-hour is used for small-scale electrical energy measurements such as battery capacity in consumer electronics. A smartphone battery typically holds 10-20 Wh, and laptop batteries range from 40 to 100 Wh.
