Unit definitions

Electronvolt

An electronvolt is the kinetic energy gained by an electron accelerating through a potential difference of one volt.

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.

How to convert Electronvolt to Food calorie (large calorie)

$$\text{Energy}_{\text{kcal}} = \text{Energy}_{\text{eV}} \cdot 3.826732736218591764593484283940002e - 23$$

Examples

Example 1

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

$$\text{Energy}_{\text{kcal}} = 45.0 \cdot 3.826732736218591764593484283940002e - 23$$

$$\text{Energy}_{\text{kcal}} = 0.000000000000000000001722029731298366294067067927773001$$

$$\therefore \ 45.0\ \text{eV} = 0.000000000000000000001722029731298366294067067927773001 \ \text{kcal}$$

Example 2

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

$$\text{Energy}_{\text{kcal}} = 90.0 \cdot 3.826732736218591764593484283940002e - 23$$

$$\text{Energy}_{\text{kcal}} = 0.000000000000000000003444059462596732588134135855546002$$

$$\therefore \ 90.0\ \text{eV} = 0.000000000000000000003444059462596732588134135855546002 \ \text{kcal}$$

Example 3

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

$$\text{Energy}_{\text{kcal}} = 120.0 \cdot 3.826732736218591764593484283940002e - 23$$

$$\text{Energy}_{\text{kcal}} = 0.000000000000000000004592079283462310117512181140728002$$

$$\therefore \ 120.0\ \text{eV} = 0.000000000000000000004592079283462310117512181140728002 \ \text{kcal}$$

Example 4

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

$$\text{Energy}_{\text{kcal}} = 150.0 \cdot 3.826732736218591764593484283940002e - 23$$

$$\text{Energy}_{\text{kcal}} = 0.000000000000000000005740099104327887646890226425910003$$

$$\therefore \ 150.0\ \text{eV} = 0.000000000000000000005740099104327887646890226425910003 \ \text{kcal}$$

Example 5

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

$$\text{Energy}_{\text{kcal}} = 175.0 \cdot 3.826732736218591764593484283940002e - 23$$

$$\text{Energy}_{\text{kcal}} = 0.000000000000000000006696782288382535588038597496895003$$

$$\therefore \ 175.0\ \text{eV} = 0.000000000000000000006696782288382535588038597496895003 \ \text{kcal}$$
