About Calorie (thermochemical) (cal)
The small calorie (cal) is the energy needed to raise one gram of water by one degree Celsius at standard pressure. While largely replaced by the joule in scientific contexts (1 cal = 4.184 J exactly), the calorie remains in use in chemistry and is the basis for the food Calorie (kilocalorie).
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.
