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.

Calorie (small calorie)

The small calorie is the thermal energy required to raise the temperature of one gram of water by one degree Celsius. It is equal to $4.184 \ \text{J}$.

How to convert Food calorie (large calorie) to Calorie (small calorie)

$$\text{Energy}_{\text{cal}} = \text{Energy}_{\text{kcal}} \cdot 1000.669216061185468451242829827916$$

Examples

Example 1

Convert $45.0\ \text{kcal}$ to $\text{cal}$.

$$\text{Energy}_{\text{cal}} = 45.0 \cdot 1000.669216061185468451242829827916$$

$$\text{Energy}_{\text{cal}} = 45030.114723$$

$$\therefore \ 45.0\ \text{kcal} = 45030.114723 \ \text{cal}$$

Example 2

Convert $80.0\ \text{kcal}$ to $\text{cal}$.

$$\text{Energy}_{\text{cal}} = 80.0 \cdot 1000.669216061185468451242829827916$$

$$\text{Energy}_{\text{cal}} = 80053.537285$$

$$\therefore \ 80.0\ \text{kcal} = 80053.537285 \ \text{cal}$$

Example 3

Convert $120.0\ \text{kcal}$ to $\text{cal}$.

$$\text{Energy}_{\text{cal}} = 120.0 \cdot 1000.669216061185468451242829827916$$

$$\text{Energy}_{\text{cal}} = 120080.305927$$

$$\therefore \ 120.0\ \text{kcal} = 120080.305927 \ \text{cal}$$

Example 4

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

$$\text{Energy}_{\text{cal}} = 150.0 \cdot 1000.669216061185468451242829827916$$

$$\text{Energy}_{\text{cal}} = 150100.382409$$

$$\therefore \ 150.0\ \text{kcal} = 150100.382409 \ \text{cal}$$

Example 5

Convert $180.0\ \text{kcal}$ to $\text{cal}$.

$$\text{Energy}_{\text{cal}} = 180.0 \cdot 1000.669216061185468451242829827916$$

$$\text{Energy}_{\text{cal}} = 180120.458891$$

$$\therefore \ 180.0\ \text{kcal} = 180120.458891 \ \text{cal}$$
