Electric Charge Converter
Convert electric charge among C, mC, Ah, mAh, and elementary charges e using coulombs as the reference.
How to use
- Enter charge quantity and choose two charge-dimension units among C, mC, Ah, mAh, and elementary charges e.
Capabilities and scope
Compare charge quantity itself with ampere-hour notation commonly used for batteries.
How it works
C is the reference: mC=0.001 C, Ah=3600 C, mAh=3.6 C, and elementary charge e=1.602176634×10⁻¹⁹ C.
Example
1000 mAh is 1 Ah, which is 3600 C.
Useful for
- Convert battery mAh into coulombs
- Compare Ah and C
- Express charge in elementary-charge scale
Before you use it
- mAh is not energy in Wh. Voltage is required to convert battery charge capacity into energy.
