A scientist repeats the Millikan oil drop experiment in a different galaxy and the charge on the drops is measured in a unit called

the electrino $($el$).$ The scientist obtains data for four drops.

Given the results of the scientist's experiment, determine the charge on an electron in electrinos.

Given that the charge on an electron is $1\mathrm{.}60{10}^{-19}C,$ determine the conversion factor between electrinos and coulombs.
