Coulombs and microcoulombs are metric measurements of electric charge, named after the French physicist CharlesAugustin de Coulomb. You can quickly convert a charge from microcoulombs to coulombs using a simple mathematical equation.
Microcoulombs and Coulombs

One coulomb, 1C, is equal to 1 million microcoulombs, 1,000,000μC  so a single microcoulomb, 1μC, is onemillionth of a coulomb, or 0.000001C. This relationship is also shown by the following equations:
1C = 1,000,000μC
1μC = 0.000001CFor example, suppose you want to convert a measurement of 2,500 microcoulombs into coulombs. Since one microcoulomb equals onemillionth of a coulomb, to get the number of coulombs equal to 2,500 microcoulombs, multiply onemillionth of a coulomb by 2,500. This can also be shown by the following calculation:
1μC = 0.000001C
1μC x 2,500 = 0.000001C x 2,500
2,500μC = 0.0025CSo 2,500 microcoulombs are equal to 0.0025 coulomb, or 2,500millionths of a coulomb.
