Overview
Electric charge quantifies the amount of electricity—1 C is the charge of ~6.24×10¹⁸ electrons. Voltage (electric potential difference) drives current—1 V means 1 J of energy per coulomb. Use this tool to pivot between common and CGS units instantly.
Formula & Methodology
We pivot through SI:
Charge: $$ Q_{C} = Q_{\rm in}\times f_{\rm from},\quad Q_{\rm out}=\frac{Q_{C}}{f_{\rm to}} $$
Voltage: $$ V_{V} = V_{\rm in}\times g_{\rm from},\quad V_{\rm out}=\frac{V_{V}}{g_{\rm to}} $$

Examples
- 2 abC → C: 2×10 = 20 C
- 100 mA·h → C: 100×3.6 = 360 C
- 5 statV → V: 5×299.792458 ≈ 1498.96 V
Frequently Asked Questions
Why 1 abC = 10 C?
In the CGS-emu system, the abcoulomb is defined so that 1 abC of charge passing yields 1 dyn·cm of force at 1 cm distance.
What’s a statvolt?
Statvolt arises in the electrostatic CGS system: 1 statV ≈ 299.79 V under SI definitions.
How accurate are these?
All factors use IUPAC/NIST definitions. Slight rounding differences may occur in legacy sources.
