The word million originates from the Italian words *mille* and *one*. The Italian word *mille* means a thousand, while the word *one* is added as a suffix to *mille*. It was referred to as *millione* in Italian. But by the late Middle English period, it had gained its shape to a *million*, as a French word. Let us know more about numbers like 1 million has how many zeros, how many zeros are in a billion, and how many zeros are in trillions.

**1. How many Digits are in a Million?**

One million is also sometimes referred to as **one thousand thousand.** Therefore, one million is a result of one thousand multiplied by one thousand. A million in number is 1,000,000. Thus, a million is **a 7-digit number**. 7-digit numbers start from a million to seven nines, that is, 9,999,999. 1 million has how many zeros? To get a detailed discussion on this, keep reading.

**2. 1 Million has how many Zeros?**

1 million is a 7-digit number with one 1 and six zeros**.** The exponent in the exponential form of one million also leads us to the **number of zeros in one million, which is 6.** In terms of language, a million being used before any word refers to *several*. For example, millions of people have attended the music fest. This sentence uses the word *million* as an expression rather than a number. The meaning of one million has extended to words from numbers because it is an extremely large natural number, which is not usually used. Hope you found out the answer to 1 million has how many zeros. (See How many Hundreds are in a Million?)

**3. How many Zeros does 100 Million have?**

A hundred million is just 10 times away from being a billion. Thus, the other way of saying 100 million, in terms of billion is, 0.1 billion. A hundred million in number is equal to 100,000,000. That is, a hundred million **has eight zeros**. (See How Much is 300 Million in Numbers?)

**4. How many Zeros are in a Billion?**

Wondering how many zeros are in a billion. Then read this. The word billion originated in French. If you are reading mindfully, you already know that the word *million* is a French word with Italian origins. This French word *million* when combined with the prefix *bi* has resulted in the word billion. This word was coined in the late 17th century.

A billion is a number acquired upon multiplying thousand and million in terms of short scale. So, a billion, therefore, is a thousand million. In numbers, a billion is equal to 1,000,000,000 on a short scale. On a long scale, a billion equals a million times a million. That is, in numbers, a billion is equal to 1,000,000,000,000.

**On a short scale, a billion has 9 zeros. While on a long scale, a billion has 12 zeros.** You might be wondering what these two scales are now! The two scales are two different types of number naming systems. The long scale is essentially derived from the powers of a million, while the short scale is from the powers of a thousand.

**5. How many Zeros are in Trillions?**

As you are aware 1 million has how many zeros, you can use the same concept and find this answer. The word trillion is a result of the combination of the French words *million* and *tri*. A trillion on a short scale is what a billion on a long scale is. That is a trillion, in numbers, on a short scale is equal to 1,000,000,000,000, which has **12 zeros.**

On a **long scale,** a trillion is equal to the cube of a million. That is, a trillion, in numbers is equal to 1,000,000,000,000,000,000 and has **18 zeros.** (See What should the abbreviation for million be M or MM?)

**6. How many Millions is 1 Billion?**

A billion is commonly referred to as a **thousand million**. So, how many millions is 1 billion? That is, on a short scale, a billion is equal to one thousand million or 1,000,000,000. A billion literally translates to a million million. In this context, on a long scale, a billion is equal to **one million million** or 1,000,000,000,000. (See How long is 1 million hours?)

**7. What is after a Billion?**

A billion is a 10-digit number that is followed by nine noughts or 999,999,999. The number that follows a billion also is a 10-digit number.**1,000,000,001 is the number that comes after a billion on a short scale.**

On a long scale, a billion in number is 1,000,000,000,000. This number is followed by 999,999,999,999. The number that follows a billion on a long scale is** 1,000,000,000,001**. On a long scale, a billion has 13-digits.

Thus, a billion is a natural number with nine zeros. A trillion is what comes after a billion with 12 zeros. (See How much is 6 million pennies?)

**8. How many 100k are in a Billion?**

If you consider a short scale, to know how many 100k are in a billion, you should divide 1,000,000,000 by 100k. 100k is referred to as one lakh. If you divide one billion by one lakh, you get a quotient of 10,000. 10,000 can also be referred to as 10k. Thus, the answer is that **there are ten thousand 100Ks in a billion on a short scale.**

If you wish to know the same for a billion on a long scale, then you should divide 1,000,000,000,000 by 100K. When you divide, you get a quotient of ten million. That means, there are **ten million 100Ks** in a billion on a short scale. (See What does k stand for in Money?)

**9. How much is a Trillion?**

Just like 1 million has how many zeros, a trillion is a natural number that is followed by 999,999,999,999 and precedes 1,000,000,000,001 on a short scale. On a short scale, a trillion in numbers is **1,000,000,000,000.**

A trillion on a long scale is equal to a quintillion on a short scale. It is followed by 999,999,999,999,999,999, and precedes 1,000,000,000,000,000,001. On a large scale, a trillion in numbers is 1,000,000,000,000,000,000. Also, check out How Long does it take to Count to 1 Trillion?

**10. How many Billions are in a Trillion?**

A billion is a million-million, and a trillion is a million-million-million on a long scale. Thus on a long scale, a trillion is a million times a billion. That is a** trillion consists of a million billion**. That means that there are a thousand billion in a trillion on a short scale.

**11. What is after a Trillion?**

A trillion in number is equal to 1,000,000,000,000 on a short scale. The natural number following a trillion on a short scale is** 1,000,000,000,001.** The number following it will be a quadrillion. On a long scale, a trillion is equal to 1,000,000,000,000,000,000. It is preceded by 1,000,000,000,000,000,001. That is, the long-scale trillion is equal to the short-scale quintillion. Thus on a long scale, a trillion is preceded by a sextillion. (See How much does a million dollars weigh in 20 dollar bills?)

**12. What is the Name for 1000 Trillion?**

Besides knowing 1 million has how many zeros, note that the difference between a million, billion, trillion, and quadrillion is three zeros. Add three zeros to a million, and you get a billion. Add three zeros to a billion, you get a trillion.

A thousand trillion is nothing but multiplying a thousand with a trillion, i.e., indirectly, adding three zeros to a trillion. When you add three zeros to a trillion, you get a **quadrillion** on a short scale. On a long scale, a trillion is a quintillion. Thus a thousand trillion, on a long scale, is equal to a **sextillion**.

Fun fact: The word billion, trillion, quadrillion, quintillion, and up to nonillion are coined by Nicolas Chuquet. (Also read What is i to the Power of 3?)
