Convert British thermal unit to Joule

Unit definitions

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.

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.

How to convert British thermal unit to Joule

$$\text{Energy}_{\text{J}} = \text{Energy}_{\text{Btu}} \cdot 1055.06$$

Examples

Example 1

Convert $35.0\ \text{Btu}$ to $\text{J}$.

$$\text{Energy}_{\text{J}} = 35.0 \cdot 1055.06$$

$$\text{Energy}_{\text{J}} = 36927.1$$

$$\therefore \ 35.0\ \text{Btu} = 36927.1 \ \text{J}$$

Example 2

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

$$\text{Energy}_{\text{J}} = 75.0 \cdot 1055.06$$

$$\text{Energy}_{\text{J}} = 79129.5$$

$$\therefore \ 75.0\ \text{Btu} = 79129.5 \ \text{J}$$

Example 3

Convert $100.0\ \text{Btu}$ to $\text{J}$.

$$\text{Energy}_{\text{J}} = 100.0 \cdot 1055.06$$

$$\text{Energy}_{\text{J}} = 105506$$

$$\therefore \ 100.0\ \text{Btu} = 105506 \ \text{J}$$

Example 4

Convert $145.0\ \text{Btu}$ to $\text{J}$.

$$\text{Energy}_{\text{J}} = 145.0 \cdot 1055.06$$

$$\text{Energy}_{\text{J}} = 152983.7$$

$$\therefore \ 145.0\ \text{Btu} = 152983.7 \ \text{J}$$

Example 5

Convert $200.0\ \text{Btu}$ to $\text{J}$.

$$\text{Energy}_{\text{J}} = 200.0 \cdot 1055.06$$

$$\text{Energy}_{\text{J}} = 211012$$

$$\therefore \ 200.0\ \text{Btu} = 211012 \ \text{J}$$
