Unit definitions

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.

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.

How to convert Elementary Charge to Coulomb

$$\text{Electric Charge}_{\text{C}} = \text{Electric Charge}_{\text{e}} \cdot 1.602176634e - 19$$

Examples

Example 1

Convert $35.0\ \text{e}$ to $\text{C}$.

$$\text{Electric Charge}_{\text{C}} = 35.0 \cdot 1.602176634e - 19$$

$$\text{Electric Charge}_{\text{C}} = 0.000000000000000005607618219$$

$$\therefore \ 35.0\ \text{e} = 0.000000000000000005607618219 \ \text{C}$$

Example 2

Convert $85.0\ \text{e}$ to $\text{C}$.

$$\text{Electric Charge}_{\text{C}} = 85.0 \cdot 1.602176634e - 19$$

$$\text{Electric Charge}_{\text{C}} = 0.000000000000000013618501389$$

$$\therefore \ 85.0\ \text{e} = 0.000000000000000013618501389 \ \text{C}$$

Example 3

Convert $105.0\ \text{e}$ to $\text{C}$.

$$\text{Electric Charge}_{\text{C}} = 105.0 \cdot 1.602176634e - 19$$

$$\text{Electric Charge}_{\text{C}} = 0.000000000000000016822854657$$

$$\therefore \ 105.0\ \text{e} = 0.000000000000000016822854657 \ \text{C}$$

Example 4

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

$$\text{Electric Charge}_{\text{C}} = 135.0 \cdot 1.602176634e - 19$$

$$\text{Electric Charge}_{\text{C}} = 0.000000000000000021629384559$$

$$\therefore \ 135.0\ \text{e} = 0.000000000000000021629384559 \ \text{C}$$

Example 5

Convert $170.0\ \text{e}$ to $\text{C}$.

$$\text{Electric Charge}_{\text{C}} = 170.0 \cdot 1.602176634e - 19$$

$$\text{Electric Charge}_{\text{C}} = 0.000000000000000027237002778$$

$$\therefore \ 170.0\ \text{e} = 0.000000000000000027237002778 \ \text{C}$$
