What Is This Tool?
This tool converts electric charge values from picocoulombs, a very small SI-derived unit, to ESU of charge, the electrostatic unit used in the Gaussian CGS system. It helps translate measurements between these two different unit systems commonly encountered in fields like plasma physics and astrophysics.

-
Convert 50 pC to ESU: 50 × 0.0029979246 = 0.14989623 ESU of charge
Common Use Cases
-
Translating charge measurements from SI units to Gaussian CGS units for research
-
Analyzing charge pulses detected by particle detectors and electrometers
-
Interpreting charge stored on small capacitors in physics experiments
-
Consulting or converting charge values from older scientific literature using CGS units
-
Performing theoretical or computational studies in plasma physics and astrophysics
Tips & Best Practices
-
Ensure consistent unit use when combining measurements from different systems
-
Understand when CGS (ESU) units are preferred to match literature or theoretical frameworks
-
Consider the physical context to apply conversions meaningfully
-
Verify conversion factors carefully especially in precision-sensitive applications
Limitations
-
ESU units belong to the non-SI Gaussian CGS system, less common in modern electrical engineering
-
Using ESU without careful unit consistency can cause confusion due to different base quantities
-
Conversion depends on correct application and the precision of the conversion factor
Frequently Asked Questions
-
What is a picocoulomb?
-
A picocoulomb (pC) is an SI-derived unit of electric charge equal to 10^-12 coulombs, used to measure very small charges.
-
What is the ESU of charge?
-
The ESU or electrostatic unit of charge is the unit for electric charge in the Gaussian CGS system, defined so that two 1 esu charges separated by 1 cm repel with 1 dyne force.
-
Why convert from picocoulombs to ESU of charge?
-
Converting allows comparison between SI and CGS unit systems, useful when analyzing experimental data or theoretical work using Gaussian units in fields like plasma physics or astrophysics.
