What is a Charge Converter?
An electric charge converter is a tool that converts between units of electric charge such as coulombs, ampere-hours, milliampere-hours, and faradays. It is essential for battery capacity calculations, electronics design, and electrochemistry applications.
How to Convert Charge Units
Select the charge unit you want to convert from and the target unit using the dropdown menus. Enter your value in the input field and the converter instantly shows the equivalent charge in your chosen unit. Common conversions like coulombs to ampere-hours are available as quick links.
Charge Conversion Formulas
History of Charge Measurement
The coulomb is named after Charles-Augustin de Coulomb, who quantified electric charge in the 1780s. The ampere-hour emerged in the 19th century as a practical unit for battery capacity. Michael Faraday introduced the faraday constant for electrochemistry, and Robert Millikan measured the elementary charge in 1909.
About This Charge Converter
This electric charge converter supports 15 units including coulomb, ampere-hour, milliampere-hour, faraday, abcoulomb, statcoulomb, franklin, and elementary charge. It handles both SI and CGS units for electrical engineering and physics.
Frequently Asked Questions
How do I convert coulombs to ampere-hours?
Divide the coulomb value by 3600 to get ampere-hours. For example, 7200 C ÷ 3600 = 2 Ah.
What is the difference between Ah and mAh?
Ah (ampere-hours) and mAh (milliampere-hours) both measure battery capacity. 1 Ah = 1000 mAh. Phone batteries are typically rated in mAh (e.g., 5000 mAh), while car batteries use Ah (e.g., 60 Ah).
How many coulombs are in one ampere-hour?
One ampere-hour equals exactly 3600 coulombs. This is because 1 Ah = 1 ampere flowing for 3600 seconds (1 hour).
What is a faraday in terms of coulombs?
One faraday equals approximately 96,485.33 coulombs. It represents the total charge of one mole of electrons and is fundamental to electrochemistry calculations.
What is the elementary charge?
The elementary charge (e) is the electric charge of a single proton, equal to approximately 1.602 × 10⁻¹⁹ coulombs. It is the smallest unit of free charge found in nature.
