What Is This Tool?

This converter transforms electric charge values from ampere-second (A*s), the SI unit, to franklin (Fr), the electrostatic charge unit in the cgs-ESU system. It enables seamless conversions crucial for classical electromagnetism, theoretical physics, and specialized scientific fields.

How to Use This Tool?

  • Enter the electric charge value in ampere-second (A*s) into the input field.
  • Select 'ampere-second [A*s]' as the input unit and 'franklin [Fr]' as the output unit.
  • Click the convert button to obtain the equivalent charge in franklin.

Key Features

  • Converts charge units between ampere-second and franklin accurately using the established conversion factor.
  • Supports use cases linking SI charge measurements to classical and theoretical physics contexts.
  • Browser-based and simple to use without requiring complex input.

Examples

  • 2 A*s converts to approximately 5,995,849,160 Fr.
  • 0.5 A*s converts to about 1,498,962,290 Fr.

Common Use Cases

  • Calculating charge delivered by current pulses in electronic circuits.
  • Coulomb counting for battery state-of-charge estimation using ampere-seconds or related units.
  • Interpreting historical electromagnetism data that uses cgs units like franklin.
  • Performing theoretical calculations in Gaussian or cgs-ESU systems to simplify electromagnetic equations.
  • Astrophysics and plasma physics research where cgs units remain standard.

Tips & Best Practices

  • Always verify input units before conversion to ensure accuracy.
  • Use this converter primarily for bridging SI and cgs-ESU measurements in theoretical or historical contexts.
  • Be mindful of large numerical values resulting from the conversion factor when performing calculations.

Limitations

  • The substantial difference between SI and cgs units results in very large numerical factors, which may complicate calculations.
  • The franklin unit is mostly confined to theoretical, historical, or specialized research, limiting its everyday practical use.

Frequently Asked Questions

What is an ampere-second?
An ampere-second (A*s) is the SI unit of electric charge representing the charge moved by a steady current of one ampere flowing for one second.

Why convert from ampere-second to franklin?
Converting helps relate modern SI charge measurements to cgs-ESU system units used in classical electromagnetism and certain scientific fields.

Is the franklin unit commonly used today?
Franklin is primarily used in theoretical and historical contexts and is rarely applied in routine modern electric charge measurements.

Key Terminology

Ampere-second (A*s)
The SI derived unit of electric charge equal to one coulomb, representing charge transferred by a one ampere current in one second.
Franklin (Fr)
An electrostatic unit of electric charge in the cgs-ESU system, also known as the statcoulomb, approximately equal to 3.33564×10⁻¹⁰ coulombs.
cgs-ESU system
The centimeter-gram-second electrostatic unit system used in classical electromagnetism and theoretical physics.
