Kilojoule

$10^{3} \ \text{J}$ is a kilojoule.

British thermal unit

The British thermal unit (Btu) is the amount of thermal energy required to raise the temperature of one pound of water by one degree Fahrenheit.

How to convert Kilojoule to British thermal unit

$$\text{Energy}_{\text{Btu}} = \text{Energy}_{\text{kJ}} \cdot 0.9478133944988910583284362974617557$$

Examples

Example 1

Convert $25.0\ \text{kJ}$ to $\text{Btu}$.

$$\text{Energy}_{\text{Btu}} = 25.0 \cdot 0.9478133944988910583284362974617557$$

$$\text{Energy}_{\text{Btu}} = 23.695335$$

$$\therefore \ 25.0\ \text{kJ} = 23.695335 \ \text{Btu}$$

Example 2

Convert $75.0\ \text{kJ}$ to $\text{Btu}$.

$$\text{Energy}_{\text{Btu}} = 75.0 \cdot 0.9478133944988910583284362974617557$$

$$\text{Energy}_{\text{Btu}} = 71.086005$$

$$\therefore \ 75.0\ \text{kJ} = 71.086005 \ \text{Btu}$$

Example 3

Convert $105.0\ \text{kJ}$ to $\text{Btu}$.

$$\text{Energy}_{\text{Btu}} = 105.0 \cdot 0.9478133944988910583284362974617557$$

$$\text{Energy}_{\text{Btu}} = 99.520406$$

$$\therefore \ 105.0\ \text{kJ} = 99.520406 \ \text{Btu}$$

Example 4

Convert $150.0\ \text{kJ}$ to $\text{Btu}$.

$$\text{Energy}_{\text{Btu}} = 150.0 \cdot 0.9478133944988910583284362974617557$$

$$\text{Energy}_{\text{Btu}} = 142.172009$$

$$\therefore \ 150.0\ \text{kJ} = 142.172009 \ \text{Btu}$$

Example 5

Convert $190.0\ \text{kJ}$ to $\text{Btu}$.

$$\text{Energy}_{\text{Btu}} = 190.0 \cdot 0.9478133944988910583284362974617557$$

$$\text{Energy}_{\text{Btu}} = 180.084545$$

$$\therefore \ 190.0\ \text{kJ} = 180.084545 \ \text{Btu}$$
