How to Convert Nanocoulombs to Coulombs

A Coulomb (C) is a rather large unit of electric charge, while the Nanocoulomb (nC) is a much smaller unit. By definition, “nano” stands for 10⁻⁹, which is equal to one-billionth.

The charge of 1 nC is:
1 nC = 10⁻⁹ C

Formula to Convert nC to C

Q(C) = Q(nC) × 10⁻⁹

Examples

Convert 7.3 × 10⁴ nC to C:
Q(C) = 7.3 × 10⁴ × 10⁻⁹ = 7.3 × 10⁻⁵ C
So, 73,000 nC = 0.000073 C (which is 73 μC)

To change nanocoulombs to coulombs, multiply the number of nanocoulombs by 10⁻⁹.
