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.
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.
