Megaelectronvolts (MeV)
Definition
A megaelectronvolt (MeV) is a unit of energy equal to 1,000,000 electronvolts, or approximately 1.602 × 10⁻¹³ joules.
History
The MeV became essential with the development of nuclear physics and particle accelerators in the mid-20th century, particularly for describing nuclear binding energies and particle collision energies.
Current use
MeV are the standard unit for nuclear reaction energies, gamma-ray spectroscopy, radiation therapy dosimetry, and high-energy particle physics experiments.
Kilocalories (kcal)
Definition
A kilocalorie (kcal), also known as a food calorie or large calorie, equals 1,000 small calories or approximately 4,184 joules. It is the standard unit for measuring dietary energy.
History
The kilocalorie became the standard unit for food energy labeling in the United States and many other countries during the 20th century. Nutritionist Wilbur Olin Atwater pioneered its use in dietary science.
Current use
Kilocalories are the primary unit for food energy on nutrition labels in the US, Canada, and much of Asia. They are also used in exercise science, dietetics, and metabolic rate calculations.
