Thanks Pedro Hernandez for the original and for the challenge of translating and editing it for English units. Let me know if I got any of the English wrong. (from Google Translate)
P.S. I attached the Excel sheet that I converted from Google Sheets but I didn't check if it came across right.
P.P.S. Of course, use this at your own risk and I make no guarantees of its sufficiency.
