What is a Faraday?
The faraday (symbol: F) is a unit of electrical charge equal to the magnitude of the charge of one mole of electrons, approximately 96,485.33 coulombs. It is named after the English scientist Michael Faraday. One faraday is equal to one elementary charge (approximately 1.602176634×10^-19 coulombs) multiplied by Avogadro's number (approximately 6.02214076×10^23 mol^-1).
The faraday is commonly used in electrochemistry to express the amount of charge transferred in electrochemical reactions. For example, when one mole of electrons is transferred in a redox reaction, one faraday of charge has been moved. Our faraday conversion tool helps you easily convert between faradays and other units like coulombs and ampere-hours.
What is the SI of Faraday?
The faraday is not an SI unit, but it is directly related to SI units. It is defined in terms of the coulomb (C), the SI unit of electric charge, and Avogadro's number. The faraday constant (F) represents the electric charge per mole of electrons and has the value 96485.3321233100184 C/mol. This makes it essential for electric charge conversion:
- 1 Faraday (F) = 96485.3321233100184 Coulombs (C)
- 1 Faraday (F) = 26.801489417948894 Ampere-hours (Ah)
- 1 Faraday (F) = 26801.489417948894 Milliampere-hours (mAh)
What are Faradays Used For?
Faradays are used primarily in electrochemistry to quantify the amount of charge transferred in electrochemical reactions. This unit is particularly useful in electric charge conversion for scientific and industrial applications:
Electroplating
Calculating the amount of metal deposited during electroplating processes. For example, determining how much copper will be deposited when a known quantity of electricity passes through a copper sulfate solution.
Battery Capacity
Understanding the total charge capacity of electrochemical cells. For example, a battery that can deliver 2 faradays of charge can theoretically produce 2 moles of electrons in its reactions.
Electrolysis
Determining the amount of substance produced or consumed in electrolysis reactions. For example, calculating how much hydrogen gas will be produced by passing 1 faraday of charge through water.
Corrosion Studies
Measuring the rate of metal loss due to electrochemical corrosion. For example, quantifying how many faradays of charge are involved in the corrosion of a steel structure over time.
Etymology and History
The unit "faraday" is named after Michael Faraday (1791-1867), the English scientist who made fundamental contributions to the study of electromagnetism and electrochemistry. Faraday's laws of electrolysis, formulated in the 1830s, established the quantitative relationship between the amount of electricity passed through an electrolyte and the amount of substance deposited or liberated at the electrodes.
The faraday constant, representing the charge of one mole of electrons, was later determined experimentally. Its value is now exactly defined as 96485.3321233100184 coulombs per mole, derived from the exact values of the elementary charge and Avogadro's number. This precise definition makes the faraday a crucial constant in electric charge conversion and modern electrochemistry.
Frequently Asked Questions
What is the value of 1 faraday in coulombs?
One faraday is equal to exactly 96485.3321233100184 coulombs. This value is derived from the elementary charge (1.602176634×10^-19 C) multiplied by Avogadro's number (6.02214076×10^23 mol^-1). This precise definition makes faraday conversion straightforward and accurate for scientific applications.
How is the faraday used in electrochemistry?
In electrochemistry, the faraday is used to calculate the amount of substance produced or consumed in electrochemical reactions. According to Faraday's laws of electrolysis, the mass of a substance deposited or dissolved at an electrode is directly proportional to the quantity of electricity (in faradays) passed through the electrolyte. This makes faraday conversion essential for battery design and electroplating processes.
Is the faraday an SI unit?
No, the faraday is not an SI unit. The SI unit for electric charge is the coulomb. However, the faraday is directly related to SI units through the faraday constant, which has the exact value of 96485.3321233100184 C/mol. When performing electric charge conversion, you can easily convert between faradays and coulombs using this constant.
How do I convert faradays to other units?
Use our faraday conversion calculators above, or multiply by the appropriate conversion factor. For example, to convert faradays to coulombs, multiply by 96485.33; to convert faradays to ampere-hours, multiply by 26.8015.

What are common uses for faraday conversion?
Faraday conversion is essential in electrochemistry (calculating reaction yields), battery technology (determining capacity), electroplating (measuring metal deposition), and corrosion science (quantifying material loss). Whether calculating the amount of copper in electroplating or determining battery capacity, our faraday converter tool simplifies these specialized electric charge conversion tasks.
How does faraday conversion differ from other electric charge units?
The faraday is unique among electric charge units because it directly relates the macroscopic quantity of charge to the microscopic count of electrons through Avogadro's number. While coulombs measure absolute charge and ampere-hours measure charge flow over time, the faraday specifically quantifies charge in terms of moles of electrons, making electric charge conversion particularly useful in chemistry applications.
