energy units
Calories and kilowatt-hours
Energy units are standardized measurements for quantifying energy—joules, calories, kilowatt-hours, British thermal units, and electron volts among the most common.
Different fields favor different units: physicists use joules, nutritionists use calories, electricians use kilowatt-hours.
The energy bill lists consumption in kilowatt-hours.
Food labels show energy content in calories.
