Deci = a factor of ten, at least use the right derivation. What you don't get is that the meaning of words sometimes change over time, how much proof do you need placed infront of you before you understand the facts. Like seriously your total inability to understand this very simple premise makes you seem to be a "yokel" as you put it, seriously how do you not get this? Were you dropped as a child or were you spiked into the ground like a football after a game winning touchdown? Seriously are you gonna start arguing that December is still the tenth month of the year just because it starts with decem?
