Unit definitions

Electronvolt

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

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 Electronvolt to British thermal unit

$$\text{Energy}_{\text{Btu}} = \text{Energy}_{\text{eV}} \cdot 1.518564311034443538756089701059655e - 22$$

Examples

Example 1

Convert $20.0\ \text{eV}$ to $\text{Btu}$.

$$\text{Energy}_{\text{Btu}} = 20.0 \cdot 1.518564311034443538756089701059655e - 22$$

$$\text{Energy}_{\text{Btu}} = 0.000000000000000000003037128622068887077512179402119311$$

$$\therefore \ 20.0\ \text{eV} = 0.000000000000000000003037128622068887077512179402119311 \ \text{Btu}$$

Example 2

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

$$\text{Energy}_{\text{Btu}} = 75.0 \cdot 1.518564311034443538756089701059655e - 22$$

$$\text{Energy}_{\text{Btu}} = 0.00000000000000000001138923233275832654067067275794742$$

$$\therefore \ 75.0\ \text{eV} = 0.00000000000000000001138923233275832654067067275794742 \ \text{Btu}$$

Example 3

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

$$\text{Energy}_{\text{Btu}} = 100.0 \cdot 1.518564311034443538756089701059655e - 22$$

$$\text{Energy}_{\text{Btu}} = 0.00000000000000000001518564311034443538756089701059655$$

$$\therefore \ 100.0\ \text{eV} = 0.00000000000000000001518564311034443538756089701059655 \ \text{Btu}$$

Example 4

Convert $140.0\ \text{eV}$ to $\text{Btu}$.

$$\text{Energy}_{\text{Btu}} = 140.0 \cdot 1.518564311034443538756089701059655e - 22$$

$$\text{Energy}_{\text{Btu}} = 0.00000000000000000002125990035448220954258525581483518$$

$$\therefore \ 140.0\ \text{eV} = 0.00000000000000000002125990035448220954258525581483518 \ \text{Btu}$$

Example 5

Convert $165.0\ \text{eV}$ to $\text{Btu}$.

$$\text{Energy}_{\text{Btu}} = 165.0 \cdot 1.518564311034443538756089701059655e - 22$$

$$\text{Energy}_{\text{Btu}} = 0.00000000000000000002505631113206831838947548006748431$$

$$\therefore \ 165.0\ \text{eV} = 0.00000000000000000002505631113206831838947548006748431 \ \text{Btu}$$
