I guess if I say
people would probably easily know what I mean, it is equal to 0.01, 1% or 1/100.
Although I am not sure whether I said it correctly.
How about 1/1,000,000,000,000,000?
I don't even know how to call the "1,000,000,000,000,000" part before I google it.
I guess most of us don't know how many zeros are in a quadrillion before looking it up.
So, I am afraid directly call that thing "one quadrillionth" is not a good idea, especially in speaking. What would I refer to it?
How about "one million billionth", as google knows it?
Could someone please give a hint? Thanks in advance.
