The idea is to divide 1 by the mass of the electron, in kilograms.
Note that you'll never get 1 kg of electrons (just by themselves) close together - the electrostatic repulsion would be enormous.
1 electron has a charge of -1.602 x 10-19 Coulombs (remember electrons are negative charged and protons positive charged particles), and a mass of 9.1095 x 10-31 kg. So divide: (-1.602 x 10-19 Coulombs per electron)/(9.1095 x 10-31 kg/electron) = -1.759 x 1011 Coulombs per kilogram. (remember electrons have a negative charge).
Also, some additional knowledge, these charges are quantized, as in there can be no charge between 1 and 2 electrons as you can not have half or one and a half and so on of electrons, and electrons have the smallest charge

There are one thousand centimeters in one kilogram. (I had to look it up on Google!)
1 kilogram = about 35.3 (35.27396195) ounces.
A kilogram is a 1000 grams - this one tenth is 100 grams.
1,000,000,000,000 nanograms are in one kilogram.
There are 1000 grams in one kilogram.
One kilogram is 32.15 troy ounces.
1000 grams is a kilogram.
One kilogram is about 2.205 pounds.

A kilogram and a kilogram are the same unit. Therefore, one kilogram is equal to one kilogram.
1 kilogram = about 35.3 (35.27396195) ounces.
The weight of one kilogram is always 1 kilogram. It doesn't matter what material you are weighing.
A kilogram is a 1000 grams - this one tenth is 100 grams.
