How to Convert Calories to Joules with a Formula

To convert calories to joules, you can use the following formula:

Joules = Calories × 4.184

Here’s a step-by-step explanation:

1. Understand the Units: A calorie (cal) is a unit of energy, and a joule (J) is also a unit of energy in the International System of Units (SI).
2. Use the Conversion Factor: The conversion factor between calories and joules is 4.184. This means that 1 calorie is equal to 4.184 joules.
3. Apply the Formula: Multiply the number of calories by 4.184 to get the equivalent energy in joules.

Example:

If you have 100 calories and want to convert it to joules:

Joules = 100 × 4.184 = 418.4 J

So, 100 calories is equal to 418.4 joules.
