How Many Zeros Are in a Million?
A million has 6 zeros. Written out it is 10,00,000 — a 1 followed by 6 zeros, 7 digits in total. The international format writes the same figure 1,000,000.
A million, written out
| Zeros | 6 |
| Total digits | 7 |
| Indian format | 10,00,000 |
| International format | 1,000,000 |
| Power of ten | 10⁶ |
| On the other scale | 10 Lakh |
| In words | Ten Lakh |
| हिन्दी | दस लाख |
Why it lands on that many
The international scale adds three zeros at each step: thousand 3, million 6, billion 9, trillion 12, quadrillion 15. Counting up in threes puts million at 6.
That rhythm is also what decides where the commas go. Indian grouping marks the last three digits and then works leftwards in pairs, mirroring the two-zero steps, which is why 10,00,000 looks nothing like 1,000,000 despite being the same number.
The quick check: the number of zeros is the exponent. Million is 10⁶, so it carries exactly 6 zeros — no counting required.

Frequently asked questions
How many zeros does a million have?
6. A million is 10,00,000, which is a 1 followed by 6 zeros and 7 digits long.
How many zeros are in 10 millions?
7. Each extra factor of ten adds one more zero, so 10 millions is 10,000,000 and 100 millions is 100,000,000.
What is a million on the other numbering system?
10 Lakh. The digits are identical; only the unit name and the comma positions change.
Do lakh and crore really have an odd number of zeros?
Yes — lakh has 5 and crore has 7. That is not a mistake but the defining feature of the Indian scale: after thousand it advances two digits at a time, so its units land on odd exponents while the international ones land on multiples of three.
