Energy Converter Calculator Guide
What is Energy Conversion?
Energy conversion translates energy quantities between units like joules (J), kilojoules (kJ), calories (cal), kilocalories (kcal), and watt-hours (Wh). Useful in nutrition, batteries, and physics experiments.
Key Relations
- 1 Wh = 3600 J
- 1 cal ≈ 4.184 J
- 1 kcal = 1000 cal ≈ 4184 J
Example
Convert 2.5 Wh to joules: 2.5 × 3600 = 9,000 J.
FAQs
Wh vs. J?
Wh measures energy over time via electrical power; J is the SI energy unit.
Calories vs. kilocalories?
Nutrition labels often use kcal; 1 kcal = 1000 cal.
