Convert Joule to Calorie (small calorie)
Unit definitions
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.
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 Joule to Calorie (small calorie)
$$\text{Energy}_{\text{cal}} = \text{Energy}_{\text{J}} \cdot 0.2390057361376673040152963671128107$$
Examples
Example 1
Convert $35.0\ \text{J}$ to $\text{cal}$.
$$\text{Energy}_{\text{cal}} = 35.0 \cdot 0.2390057361376673040152963671128107$$
$$\text{Energy}_{\text{cal}} = 8.365201$$
$$\therefore \ 35.0\ \text{J} = 8.365201 \ \text{cal}$$
Example 2
Convert $90.0\ \text{J}$ to $\text{cal}$.
$$\text{Energy}_{\text{cal}} = 90.0 \cdot 0.2390057361376673040152963671128107$$
$$\text{Energy}_{\text{cal}} = 21.510516$$
$$\therefore \ 90.0\ \text{J} = 21.510516 \ \text{cal}$$
Example 3
Convert $120.0\ \text{J}$ to $\text{cal}$.
$$\text{Energy}_{\text{cal}} = 120.0 \cdot 0.2390057361376673040152963671128107$$
$$\text{Energy}_{\text{cal}} = 28.680688$$
$$\therefore \ 120.0\ \text{J} = 28.680688 \ \text{cal}$$
Example 4
Convert $140.0\ \text{J}$ to $\text{cal}$.
$$\text{Energy}_{\text{cal}} = 140.0 \cdot 0.2390057361376673040152963671128107$$
$$\text{Energy}_{\text{cal}} = 33.460803$$
$$\therefore \ 140.0\ \text{J} = 33.460803 \ \text{cal}$$
Example 5
Convert $200.0\ \text{J}$ to $\text{cal}$.
$$\text{Energy}_{\text{cal}} = 200.0 \cdot 0.2390057361376673040152963671128107$$
$$\text{Energy}_{\text{cal}} = 47.801147$$
$$\therefore \ 200.0\ \text{J} = 47.801147 \ \text{cal}$$
