My name is James and i am the parent of a middle school student.
My question is - How would I express 6,000,000,000,000,000,000 in words?Hi James,
According to my handy Oxford Dictionary, a quintillion is one thousand raised to the sixth power. Since 1000 = 103 or 10 raised to the third power, and we have, by the rules of exponents (103)6 = 103*6 = 1018 or 10 raised to the 18th power. In your question you have the number 6,000,000,000,000,000,000 or 6 followed by 18 zeros. This is in fact, 6 times 10 raised to the 18th power, and so your number could be expressed in words as "six quintillion".
Hope this helps,
I agree with Leeanne's answer because the email address you sent us indicates that you are in the United States. If you lived in Britain then the answer would be "six trillion". There is a table of such "word" in an answer to an earlier question by MahabirHarley
