Let’s get started!
1. Statcoulombs and Kilocoulombs
What is a Statcoulomb (statC)?
A statcoulomb (statC), also known as an electrostatic unit of charge (esu), is a unit of electric charge in the CGS system. It is defined as the charge that exerts a force of 1 dyne on an equal charge placed 1 centimeter away in a vacuum.
🔹 1 statC ≈ 3.33564 × 10⁻¹⁰ coulombs (C)
What is a Kilocoulomb (kC)?
A kilocoulomb (kC) is an SI unit of electric charge equal to 1,000 coulombs (C). It is commonly used in high-capacity electrical systems, such as battery storage and industrial applications.
🔹 1 kC = 1,000 C = 10³ C
2. Conversion Formula: Statcoulomb to Kilocoulomb
Since 1 statC ≈ 3.33564 × 10⁻¹⁰ C, we can convert statcoulombs to kilocoulombs using the following formula:Kilocoulombs (kC)=Statcoulombs (statC)×3.33564×10−13Kilocoulombs (kC)=Statcoulombs (statC)×3.33564×10−13
Explanation:
- First, convert statC to C by multiplying by 3.33564 × 10⁻¹⁰.
- Then, convert C to kC by dividing by 1,000 (or multiplying by 10⁻³).
- Combining these steps gives the factor 3.33564 × 10⁻¹³.
