About Microcoulombs
The microcoulomb (µC) equals 10⁻⁶ C, used for moderate capacitors, piezoelectric charge outputs, and laboratory electrostatics. A 1 µF capacitor at 1 V holds exactly 1 µC; piezoelectric accelerometers generate charge signals in the microcoulomb range under mechanical loading. 1 µC = 10⁻³ mC = 10³ nC.
About Ampere-hours
The ampere-hour (Ah) equals exactly 3 600 C and is the universal capacity unit for rechargeable batteries. Lead-acid car batteries are rated 40-100 Ah; EV traction packs use 50-300 Ah cells; industrial forklift batteries exceed 1 000 Ah. Multiplying Ah by nominal voltage gives watt-hours of stored energy. 1 Ah = 3 600 C = 1 000 mAh.
