How to Convert Joules to Calories
Converting joules to calories is common in nutrition and thermodynamics. One calorie equals approximately 4.184 joules.
To convert joules to calories, divide the joule value by 4.184. For example, 1000 J / 4.184 = 239 calories. Note that food Calories are actually kilocalories (1 Cal = 1000 cal = 4184 J).
Understanding this conversion helps bridge physics and nutrition energy measurements.
Quick Tips
- 1 mile = 1.609 km (miles are bigger)
- 1 kg = 2.205 lbs (roughly double + 10%)
- Temperature: (°F - 32) × 5/9 = °C
