Unit definitions

Food calorie (large calorie)

$10^{3}$ small calories is a food calorie. When we talk about calories in our food, we usually mean large calories.

Joule

The joule is the SI unit of energy. It is defined as the work done when a force of one newton is applied over a distance of one meter.

How to convert Food calorie (large calorie) to Joule

$$\text{Energy}_{\text{J}} = \text{Energy}_{\text{kcal}} \cdot 4186.8$$

Examples

Example 1

Convert $40.0\ \text{kcal}$ to $\text{J}$.

$$\text{Energy}_{\text{J}} = 40.0 \cdot 4186.8$$

$$\text{Energy}_{\text{J}} = 167472$$

$$\therefore \ 40.0\ \text{kcal} = 167472 \ \text{J}$$

Example 2

Convert $90.0\ \text{kcal}$ to $\text{J}$.

$$\text{Energy}_{\text{J}} = 90.0 \cdot 4186.8$$

$$\text{Energy}_{\text{J}} = 376812$$

$$\therefore \ 90.0\ \text{kcal} = 376812 \ \text{J}$$

Example 3

Convert $110.0\ \text{kcal}$ to $\text{J}$.

$$\text{Energy}_{\text{J}} = 110.0 \cdot 4186.8$$

$$\text{Energy}_{\text{J}} = 460548$$

$$\therefore \ 110.0\ \text{kcal} = 460548 \ \text{J}$$

Example 4

Convert $150.0\ \text{kcal}$ to $\text{J}$.

$$\text{Energy}_{\text{J}} = 150.0 \cdot 4186.8$$

$$\text{Energy}_{\text{J}} = 628020$$

$$\therefore \ 150.0\ \text{kcal} = 628020 \ \text{J}$$

Example 5

Convert $175.0\ \text{kcal}$ to $\text{J}$.

$$\text{Energy}_{\text{J}} = 175.0 \cdot 4186.8$$

$$\text{Energy}_{\text{J}} = 732690$$

$$\therefore \ 175.0\ \text{kcal} = 732690 \ \text{J}$$
