How many mAh is one faraday?

One faraday equals 96485 coulombs. Since 1 mAh = 3.6 coulombs, one faraday = 96485 ÷ 3.6 ≈ 26,801.37 mAh (or about 26.801 Ah).

What is the Faraday constant?

The Faraday constant (F) is the electric charge of one mole of electrons: 96485.33212 C/mol (2018 CODATA value). It equals Avogadro's number × the elementary charge.

Why divide by 3.6 to get mAh?

1 ampere-hour = 3600 coulombs, so 1 milliampere-hour = 3.6 coulombs. Dividing a charge in coulombs by 3.6 gives the equivalent in mAh.

Is the faraday the same as the farad?

No. The farad (F) measures electrical capacitance (charge stored per volt). The faraday is an electrochemical unit of charge equal to 96485 coulombs. They share a name and symbol but measure different things — context distinguishes them.

When are faradays used instead of mAh?

Faradays appear in electrochemistry — electrolysis, electroplating, and cell reactions — where charge is counted in moles of electrons. mAh is preferred for battery ratings and consumer electronics. This tool bridges the two domains.
