Convert Food calorie (large calorie) to Kilojoule
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.
Kilojoule
$10^{3} \ \text{J}$ is a kilojoule.
How to convert Food calorie (large calorie) to Kilojoule
$$\text{Energy}_{\text{kJ}} = \text{Energy}_{\text{kcal}} \cdot 4.1868$$
Examples
Example 1
Convert $25.0\ \text{kcal}$ to $\text{kJ}$.
$$\text{Energy}_{\text{kJ}} = 25.0 \cdot 4.1868$$
$$\text{Energy}_{\text{kJ}} = 104.67$$
$$\therefore \ 25.0\ \text{kcal} = 104.67 \ \text{kJ}$$
Example 2
Convert $60.0\ \text{kcal}$ to $\text{kJ}$.
$$\text{Energy}_{\text{kJ}} = 60.0 \cdot 4.1868$$
$$\text{Energy}_{\text{kJ}} = 251.208$$
$$\therefore \ 60.0\ \text{kcal} = 251.208 \ \text{kJ}$$
Example 3
Convert $100.0\ \text{kcal}$ to $\text{kJ}$.
$$\text{Energy}_{\text{kJ}} = 100.0 \cdot 4.1868$$
$$\text{Energy}_{\text{kJ}} = 418.68$$
$$\therefore \ 100.0\ \text{kcal} = 418.68 \ \text{kJ}$$
Example 4
Convert $130.0\ \text{kcal}$ to $\text{kJ}$.
$$\text{Energy}_{\text{kJ}} = 130.0 \cdot 4.1868$$
$$\text{Energy}_{\text{kJ}} = 544.284$$
$$\therefore \ 130.0\ \text{kcal} = 544.284 \ \text{kJ}$$
Example 5
Convert $175.0\ \text{kcal}$ to $\text{kJ}$.
$$\text{Energy}_{\text{kJ}} = 175.0 \cdot 4.1868$$
$$\text{Energy}_{\text{kJ}} = 732.69$$
$$\therefore \ 175.0\ \text{kcal} = 732.69 \ \text{kJ}$$
