585 calories is equal to 2447.94 joules.
The calorie (cal) is a unit of energy commonly used in chemistry and nutrition, while the joule (J) is the SI unit of energy. Converting calories to joules involves multiplying the calorie value by the exact conversion factor of 4.184, because one calorie equals 4.184 joules. So, 585 cal × 4.184 = 2447.94 J.

Conversion Formula
The formula to convert calories (cal) to joules (J) is:
Energy (J) = Energy (cal) × 4.184
This works because one calorie is defined as the amount of heat energy needed to raise the temperature of 1 gram of water by 1 degree Celsius, which is equivalent to 4.184 joules. The joule, as the SI unit, measures energy more precisely across scientific fields.
Example calculation for 585 cal:
- Start with the value in calories: 585 cal
- Multiply by the conversion factor: 585 × 4.184

Conversion Definitions
Calorie (cal): A calorie is an unit of energy measuring the heat required to raise 1 gram of water 1 degree Celsius. It is commonly used in chemistry and nutrition, but it is not part of the International System of Units (SI). This value is often referred to as the small calorie or gram calorie.
Joule (J): The joule is the SI unit of energy, equal to the work done when a force of one newton moves an object one meter in direction of the force. It measures energy in physics, engineering, and other sciences, representing kinetic, potential, thermal, and electrical energies.
Conversion FAQs
Why does one calorie equal exactly 4.184 joules?
The value 4.184 comes from experimental measurements defining the calorie in terms of heat energy. It was standardized by international agreement based on the energy needed to heat water. This precise conversion ensures consistent energy measurement across units.
Can I convert dietary Calories (with capital C) to joules the same way?
No, dietary Calories (kilocalories) are 1000 times bigger than small calories. To convert dietary Calories to joules, multiply by 4184 instead of 4.184. Confusing the two leads to large errors in energy calculations.
What happens if I multiply calories by a wrong conversion factor?
Using incorrect factors will give wrong joule values, affecting energy estimations in scientific or nutrition contexts. Always use 4.184 for small calories to joules, or 4184 for dietary Calories, to ensure accuracy.
Is joule a better unit to use than calorie?
Joule is the SI unit and more universally accepted in scientific communities. Calories are common in food energy context. Joules allow more precise and standardized energy quantification, especially in physics and engineering.
How precise is the 4.184 conversion factor?
The factor 4.184 is exact by international agreement but the calorie itself can vary slightly depending on definition (thermochemical or international calorie). For most purposes, 4.184 is precise enough for accurate conversions.
