Coulombs Converter Calculator
Convert electric charge between coulombs (C), milli/µ/nano-coulombs, and ampere-hours (Ah↔C) instantly with this fast, accurate Coulombs Converter.
ampere hour to coulomb:
The Coulombs Converter instantly converts electric charge between coulombs, milli/u/nano-coulombs, and ampere-hours. Using q = I x t and 1Ah=3600C, it delivers fast, precise results for labs and engineering. Convert charge instantly between C, mC, µC, nC, and Ah. Based on q = I × t with exact SI prefixes and 1 Ah = 3600 C, the tool ensures accurate, lab-ready outputs.
Formula & Table Summary:
q = I × t (C = A × s)
1 C = 1000 mC = 10^6 µC = 10^9 nC1 mC = 10^-3 C,1 µC = 10^-6 C,1 nC = 10^-9 C1 Ah = 3600 C,1 mAh = 3.6 C
coulombs converter online
A Coulombs Converter is a fast, portable tool for converting among the units coulomb (C), milli-coulomb (mC), micro-coulomb (uC), nano-coulomb (nC), and ampere-hour (Ah). Electric charge is the amount of electricity and is the basic concept in electronics, physics, and engineering. The SI unit is the coulomb (C), defined in terms of current and time: q = I x t. Typical applications are to convert sensor values (uC), discharge capacitor values (mC), electrostatic measurements (nC), or battery charge values (Ah) into coulombs for evaluation. This converter uses precision factors to remove manual math: 1Ah = 3600C. It is a valuable tool for students performing circuit problems, engineers sizing components, and researchers comparing measurements between instruments. With a simple input/output workflow and accurate constants, the Coulombs Converter saves time, prevents errors, and is ideal for use in labs, classrooms, and technical documentation.
Sample Input → Output
| Input | From Unit | Conversion | To Unit | Output |
|---|---|---|---|---|
| 1 | C | × 1000 | mC | 1000 |
| 750 | µC | × 10^-6 | C | 0.00075 |
| 25,000 | nC | × 10^-9 | C | 0.000025 |
| 1.5 | Ah | × 3600 | C | 5400 |
| 500 | mAh | × 3.6 | C | 1800 |
