Extract data and text from .csv file and save to a text file

Question

I am trying to use this CsvHelper from https://github.com/JoshClose/CsvHelper/blob/master/src/CsvHelper.Example/Program.cs

to extract relevant information and save it to a text file.

if the Measured Value (F) is already in the exponential form 

9.79E-11

in the Excel file, how are we able to extract out the value such that it is 97.92pF in the text file, without manipulating the Excel file contents?

how to manipulate to show the Frequency in Hz, kHz and MHz?

appreciate any useful comment and help.
