A joule (J) is the SI derived unit of energy, work, and heat defined as the energy transferred when a force of one newton moves an object one meter.

What does kilocalorie (th) mean?

Kilocalorie (thermochemical), symbolized as kcal (th), equals 1,000 thermochemical calories and is defined as exactly 4,184 joules, commonly used in food energy and thermal contexts.

Why convert joules to kilocalorie (th)?

This conversion helps express energy in units common in nutrition and thermochemical engineering, bridging SI units with traditional heat and dietary measurements.
