1000000000 is expressed as 1 billion or One Hundred crore. In the international number system, one thousand million is considered equal to 1 billion; thus, we express 1000000000 as One Billion in words. In the Indian number system, 1000000000 is written as One Hundred Crore. 1000000000 is the numerical form of the cardinal number one billion, which represents the count or quantity of something. For example, If a government has launched its budget of 1000000000 rupees for the health department for the year 2022-2023, we will say, “Government has decided on a budget of one billion rupees for the financial year 2022-2023.”

In this article, we will understand how to derive the word form of numbers in both the international number system and the Indian number system. We will also learn some interesting facts and mathematical expansion of the number to understand the place value chart properly.

We follow a two-step process to find out the word form of the number. As we can see that there are two systems to the number, we will cover the two-step process twice.

On making a place value chart for 1000000000 in the International Number System:-

In the first step, we create a place value chart for the number 1000000000. The number has ten digits; therefore, we will assign digits the place values up to 10 places.

One Billion | One Hundred Million | Ten Million | Million | Hundred Thousand | Ten Thousand | Thousand | Hundred | Ten | One |

1 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |

In the chart above, we have assigned a place value to every digit of the number as per their standing in the number. The first digit 1 is positioned at one billion place value, the second digit 0 is placed at one hundred million place value, the third digit 0 is assigned to ten million, and 0 is given to the rest of all the place values.

After assigning the place values to their respective numbers, we read the digits from right to left along with their place values. On reading the digits from the above chart, 1000000000 is read as One billion in word form.

**Similarly, on creating a place value chart for 1000000000 in the Indian Number System:-**

Similar to the above chart, in the first step, we are creating a place value chart in the Indian number system for 1000000000. We will assign a place value to every digit of the number as per its standing in the place value chart. As the number has ten digits, we assign place values from one hundred crores to one.

One Hundred Crore | Ten Crore | Crore | Ten Lakh | Lakh | Ten Thousand | Thousand | Hundred | Ten | One |

1 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |

We have distributed the digits of the number respective to their place values. The first digit 1 stands at One hundred crore, and 0 is placed at the rest of the place values.

In the next step, we will read the number from right to left. On reading the number, 1000000000 will be read as One Hundred crore. For example, suppose the population of a country Z is 1000000000; in that case, we will say, “One Hundred Crore people reside in country Z.

**Important Note:-** Reading the digits from right to left each time is necessary.

**According to the International Number System:-**

\begin{aligned}

& 1 \times \text { One Billion }+0 \times \text { One Hundred Million }+0 \times \text { Ten Million }+0 \times \text { Million }+0 \times \text { Hundred Thousand }+0 \\

& \times \text { Ten thousand }+0 \times \text { Thousand }+0 \times \text { Hundred }+0 \times \text { Ten }+0 \times \text { One } \\

& =1 \times 1000000000+0 \times 100000000+0 \times 10000000+0 \times 1000000+0 \times 100000+0 \times 10000+0 \times \\

& 1000+0 \times 100+0 \times 10+0 \times 1

\end{aligned}

**According to the Indian Number System:-**

\begin{aligned}

& 1 \times \text { One Hundred Crore }+0 \times \text { Ten Crore }+0 \times \text { Crore }+0 \times \text { Ten Lakhs }+0 \times \text { Lakhs }+0 \times \text { Ten thousand }+ \\

& 0 \times \text { Thousand }+0 \times \text { Hundred }+0 \times \text { Ten }+0 \times \text { One } \\

& =1 \times 1000000000+0 \times 100000000+0 \times 10000000+0 \times 1000000+0 \times 100000+0 \times 10000+0 \times \\

& 1000+0 \times 100+0 \times 10+0 \times 1

\end{aligned}
