Unit definitions

Coulomb

The coulomb, named after French physicist Charles Augustin de Coulomb (1736-1806), is the SI unit of electric charge. It is defined as the amount of charge carried by an ampere of current in a second.

Elementary Charge

The elementary charge represents the charge carried by a single electron ($-1\, \text{e}$) or a proton($+1\, \text{e}$). It is equal to $1.602\,176\,634 \times 10^{-19}$ coulombs.

How to convert Coulomb to Elementary Charge

$$\text{Electric Charge}_{\text{e}} = \text{Electric Charge}_{\text{C}} \cdot 6241509074460762607.776240980930446$$

Examples

Example 1

Convert $25.0\ \text{C}$ to $\text{e}$.

$$\text{Electric Charge}_{\text{e}} = 25.0 \cdot 6241509074460762607.776240980930446$$

$$\text{Electric Charge}_{\text{e}} = 156037726861519065194.406025$$

$$\therefore \ 25.0\ \text{C} = 156037726861519065194.406025 \ \text{e}$$

Example 2

Convert $60.0\ \text{C}$ to $\text{e}$.

$$\text{Electric Charge}_{\text{e}} = 60.0 \cdot 6241509074460762607.776240980930446$$

$$\text{Electric Charge}_{\text{e}} = 374490544467645756466.574459$$

$$\therefore \ 60.0\ \text{C} = 374490544467645756466.574459 \ \text{e}$$

Example 3

Convert $115.0\ \text{C}$ to $\text{e}$.

$$\text{Electric Charge}_{\text{e}} = 115.0 \cdot 6241509074460762607.776240980930446$$

$$\text{Electric Charge}_{\text{e}} = 717773543562987699894.267713$$

$$\therefore \ 115.0\ \text{C} = 717773543562987699894.267713 \ \text{e}$$

Example 4

Convert $135.0\ \text{C}$ to $\text{e}$.

$$\text{Electric Charge}_{\text{e}} = 135.0 \cdot 6241509074460762607.776240980930446$$

$$\text{Electric Charge}_{\text{e}} = 842603725052202952049.792532$$

$$\therefore \ 135.0\ \text{C} = 842603725052202952049.792532 \ \text{e}$$

Example 5

Convert $175.0\ \text{C}$ to $\text{e}$.

$$\text{Electric Charge}_{\text{e}} = 175.0 \cdot 6241509074460762607.776240980930446$$

$$\text{Electric Charge}_{\text{e}} = 1092264088030633456360.842172$$

$$\therefore \ 175.0\ \text{C} = 1092264088030633456360.842172 \ \text{e}$$
