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.

Therm

$100\,000$ British thermal units is a therm.

How to convert Food calorie (large calorie) to Therm

$$\text{Energy}_{\text{thm}} = \text{Energy}_{\text{kcal}} \cdot 0.00003968305120087957083009497090212879$$

Examples

Example 1

Convert $35.0\ \text{kcal}$ to $\text{thm}$.

$$\text{Energy}_{\text{thm}} = 35.0 \cdot 0.00003968305120087957083009497090212879$$

$$\text{Energy}_{\text{thm}} = 0.001389$$

$$\therefore \ 35.0\ \text{kcal} = 0.001389 \ \text{thm}$$

Example 2

Convert $75.0\ \text{kcal}$ to $\text{thm}$.

$$\text{Energy}_{\text{thm}} = 75.0 \cdot 0.00003968305120087957083009497090212879$$

$$\text{Energy}_{\text{thm}} = 0.002976$$

$$\therefore \ 75.0\ \text{kcal} = 0.002976 \ \text{thm}$$

Example 3

Convert $105.0\ \text{kcal}$ to $\text{thm}$.

$$\text{Energy}_{\text{thm}} = 105.0 \cdot 0.00003968305120087957083009497090212879$$

$$\text{Energy}_{\text{thm}} = 0.004167$$

$$\therefore \ 105.0\ \text{kcal} = 0.004167 \ \text{thm}$$

Example 4

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

$$\text{Energy}_{\text{thm}} = 150.0 \cdot 0.00003968305120087957083009497090212879$$

$$\text{Energy}_{\text{thm}} = 0.005952$$

$$\therefore \ 150.0\ \text{kcal} = 0.005952 \ \text{thm}$$

Example 5

Convert $200.0\ \text{kcal}$ to $\text{thm}$.

$$\text{Energy}_{\text{thm}} = 200.0 \cdot 0.00003968305120087957083009497090212879$$

$$\text{Energy}_{\text{thm}} = 0.007937$$

$$\therefore \ 200.0\ \text{kcal} = 0.007937 \ \text{thm}$$
