Coulomb

Measurement units: electrical charge
Symbol: C
multiplesCoulomb (C): multiples and submultiples
Ampere hours to coulombs Coulombs to ampere hours

info Symbol: C

1 C = 1 A × 1 s.

The coulomb is the International System of Units (SI) unit of electric charge.

The coulomb is exactly 1/(1.602176634×10-19) elementary charges.

The same number of electrons has the same magnitude but opposite sign of charge, that is, a charge of −1 C.
