Electron Charge to Coulombs Conversion

One electron charge is equal to 0.0000000000000000001602176634 coulombs, so turning a charge given in electron charges into coulombs is a single multiplication. Enter an amount in electron charge, press Convert, and the matching charge in coulombs is shown.

About the two units

Electric charge can be stated as a number of electron charges, written as e, or in coulombs, written as C. The electron charge is the tiny packet of charge carried by one electron, while the coulomb is the much larger unit this calculator reports its answer in.

Because the two units differ by nineteen orders of magnitude, a charge of a few electron charges becomes a decimal point followed by eighteen zeros before any digits appear. Writing the factor in full, as 0.0000000000000000001602176634, keeps the relationship unambiguous.

How to convert electron charge to coulombs

Multiply the charge in electron charges by 0.0000000000000000001602176634 to obtain the charge in coulombs. Going the other way, one coulomb is worth about 6.241509074 × 10^18 electron charges, so dividing a coulomb figure by the factor returns the charge in electron charges.

Type your value in the electron charge field, press Convert, and read the outcome next to the coulomb label. Copy puts the result on your clipboard and Clear empties the field for the next calculation.

Electron charge to coulombs formula

Q(C) = Q(e) × 0.0000000000000000001602176634, where Q(e) is the charge measured in electron charges and Q(C) is the same charge measured in coulombs.

For a charge of 3 electron charges: Q(C) = 3 × 0.0000000000000000001602176634 = 4.806529902 × 10^-19 C, or about 4.8065 × 10^-19 C.
