-
100 Franklin [Fr] converts to about 3.33564×10⁻⁵ Millicoulomb [mC].
Common Use Cases
-
Expressing electrostatic charge values from classical electromagnetism literature in modern engineering units.
-
Measuring charge in medical devices such as neural stimulators that deliver pulses in the milllicoulomb range.
-
Reporting charge in capacitor discharges and transient pulses during electronics testing.
-
Conducting electrochemical measurements in laboratory experiments requiring precise charge quantification.
Tips & Best Practices
-
Ensure correct unit selection before converting to avoid errors.
-
Use millicoulomb output for engineering contexts where charges are smaller than a coulomb but larger than microcoulomb scales.
-
Refer to example conversions to confirm expected orders of magnitude.
-
Be aware that franklin is mainly theoretical and historically applied; use millicoulomb for practical measurements.
Limitations
-
Franklin is largely a theoretical and historical unit rarely used in practical electrical engineering applications.
-
Conversion precision may be affected by rounding due to the very small conversion coefficient.
-
Millicoulombs may not be suitable for measuring extremely small charges at micro- or nano-scales, where other units like microcoulombs or coulombs may be preferable.
Frequently Asked Questions
-
What is the franklin unit used for?
-
The franklin is an electrostatic unit of electric charge historically used in the cgs-ESU system, commonly found in classical electromagnetism and certain physics research contexts.
-
Why convert from franklin to millicoulomb?
-
Converting to millicoulomb provides a more practical and engineering-friendly unit for measuring electric charge in modern electronics, medical devices, and experiments.
-
Is the millicoulomb unit suitable for all charge measurements?
-
Millicoulomb is ideal for charges smaller than a coulomb but may be too large for very small charges that require microcoulomb or smaller units.
Key Terminology
-
Franklin [Fr]
-
An electrostatic unit of electric charge in the cgs-ESU system, also called statcoulomb, historically used in classical electromagnetism.
-
Millicoulomb [mC]
-
A unit of electric charge equal to one-thousandth of a coulomb, useful for representing smaller charges in electrical engineering and experiments.
