About These Units
Coulomb (C)
The coulomb (C) is the SI unit of electric charge, defined as the charge transferred by 1 ampere flowing for 1 second. One coulomb equals 6.242×10¹⁸ elementary charges (electrons or protons). Named after physicist Charles-Augustin de Coulomb. Formula: Q = I × t (charge = current × time).
Microampere-hour (μAh)
A microampere-hour (μAh) equals 0.0036 coulombs or 0.001 mAh. Used for tiny batteries: hearing aids (30-300 μAh), watch batteries (20-200 μAh), IoT sensors, and implantable medical devices. Enables runtime calculations for low-power circuits.
