Enter charge in coulombs:

Conversions:

1 Coulomb (C) = 6.24150975×10¹⁸ Electron Charge (e)

1 Electron Charge (e) = 1.60217646×10^-19 Coulombs (C)

Conversion Formula:

Q(e) = Q(C) × 6.24150975×10¹⁸

Q(C) = Q(e) × 1.60217646×10^-19

Example:

Convert 3 coulombs to electron charge:

Q(e) = 3C × 6.24150975×10¹⁸ = 1.872×10¹⁹e

Conversion Result:

3 coulombs is equal to 1.872×10¹⁹ electron charge.

The Coulombs to Electron Charge Converter is a tool used to convert electric charge values from Coulombs (C) to electron charge (e). This conversion is essential in particle physics, quantum mechanics, and electronics, where charge is often expressed in terms of the fundamental charge of an electron.

Understanding the Units

1. Coulomb (C)

• The Coulomb (C) is the SI unit of electric charge.

• Defined as the charge transported by a constant current of 1 ampere (A) in 1 second (s):

  $$1\text{ C}=1\text{ A}\times 1\text{ s}$$

• Used in large-scale electrical systems.

2. Electron Charge (e)

• The electron charge (e) is the fundamental charge of a single proton (or the negative charge of an electron).

• Its magnitude is approximately:

  $$1\text{ e}\approx 1.602176634\times {10}^{-19}\text{ C}$$

• Used in atomic-scale calculations (e.g., semiconductor physics, quantum electrodynamics).

Conversion Formula

The conversion between Coulombs (C) and electron charge (e) is given by:

$$\text{Number of electron charges (e)}=\frac{\text{Charge in Coulombs (C)}}{1.602176634\times {10}^{-19}}$$$$\text{Charge in Coulombs (C)}=\text{Number of electron charges (e)}\times 1.602176634\times {10}^{-19}$$

Example Conversions

Coulombs (C)	Electron Charge (e)
1 C	≈ 6.2415 × 10¹⁸ e
1.602176634 × 10⁻¹⁹ C	= 1 e (exact)
0.5 C	≈ 3.12075 × 10¹⁸ e
2 C	≈ 1.2483 × 10¹⁹ e
1 × 10⁻⁶ C (1 μC)	≈ 6.2415 × 10¹² e

How to Use a Coulombs to Electron Charge Converter

1. Manual Calculation

Divide the Coulomb value by 1.602176634 × 10⁻¹⁹ to get the number of electron charges:

$$\text{Example: }2\text{ C}=\frac{2}{1.602176634\times {10}^{-19}}\approx 1.2483\times {10}^{19}\text{ e}$$
