What Is This Tool?
This tool allows you to convert electric charge values measured in ampere-seconds (A·s), the SI unit for charge, to statcoulombs (stC), the cgs-ESU unit of charge used in specific scientific fields like plasma physics and astrophysics.
How to Use This Tool?
-
Enter the value in ampere-seconds that you wish to convert
-
Select ampere-second [A*s] as the input unit
-
Choose statcoulomb [stC] as the target unit
-
Click convert to get the equivalent charge in statcoulombs
Key Features
-
Conversion between ampere-second and statcoulomb units of electric charge
-
Based on an exact conversion rate relating SI and Gaussian cgs units
-
Supports understanding and comparing charge measurements across different unit systems
-
Browser-based and easy to use without special software
Examples
-
2 A·s converts to approximately 5995849159.9992 stC
-
0.5 A·s converts to approximately 1498962289.9998 stC
Common Use Cases
-
Calculating charge transferred in electronic circuits during current pulses
-
Expressing charge values in older scientific research that use Gaussian units
-
Comparing modern SI-based experimental data with historical charge measurements
-
Conducting plasma physics and astrophysics calculations requiring cgs units
Tips & Best Practices
-
Ensure the correct units are selected before conversion to avoid errors
-
Use this conversion when working with theoretical or historical data presented in Gaussian units
-
Consider the context of your scientific field and unit system conventions when interpreting results
Limitations
-
The statcoulomb is not an SI unit and is rarely used outside specialized scientific contexts
-
Conversion precision may be affected by rounding of the fixed conversion factor
-
Differences in fundamental constants between SI and cgs-ESU systems affect interpretations beyond simple unit conversion
Frequently Asked Questions
-
What is an ampere-second?
-
An ampere-second is the SI unit of electric charge, equivalent to the charge transported by a current of one ampere flowing for one second.
-
What is a statcoulomb?
-
A statcoulomb is the electrostatic unit of charge in the Gaussian cgs system, used mainly in theoretical and historical contexts.
-
Why convert from ampere-seconds to statcoulombs?
-
Conversion helps relate modern SI measurements to older or specialized scientific work that uses the Gaussian unit system for charge.
Key Terminology

Statcoulomb [stC]
-
The cgs-ESU (Gaussian) unit of electric charge used primarily in theoretical physics and historical scientific calculations.
-
Charge
-
A fundamental property of matter that causes it to experience a force when placed in an electromagnetic field.
