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. Drop Calculated charge (el)
A 5.52×10−14 el
B 4.14×10−14 el
C 5.06×10−14 el
D 2.76×10−14 el
Given the results of the scientist's experiment, determine the charge on an electron in electrinos.

Given that the charge on an electron is 1.60×10−19 C , determine the conversion factor between electrinos and coulombs.
1 C= ? el
