Frequently Asked Questions
-
What is a microcoulomb?
-
A microcoulomb (µC) is an SI derived unit of electric charge equal to one millionth of a coulomb, measuring electric charge transfer or storage.
-
Why use franklin units instead of coulombs?
-
Franklin (Fr) units belong to the cgs-ESU system and are useful in classical electromagnetism, simplifying theoretical calculations and appearing in historical literature.
-
Is the conversion exact for practical use?
-
The conversion uses a precise conversion rate, but rounding may slightly affect outcomes in highly sensitive measurements.
