How many zeros are in a million?

There are six zeros following the one in one million. One million is written as 1,000,000 or in exponential form as 1 x 10^6, which means that it is equal to 10 x 10 x 10 x 10 x 10 x 10.

One thousand has three zeros, 10 thousand has four and 100 thousand has five. These numbers are written exponentially as 10^3, 10^4 and 10^5 respectively. One billion has nine zeros and is written as 10^9. The exponent following the 10 each time represents the number of zeros at the end of the number itself. Other larger numbers include a trillion with 12 zeros, quadrillion with 15 zeros, quintillion with 18 zeros and sextillion with 21 zeros.
