Numbers in Words in International System
The international system has different place value names for a certain position of a digit in a number. For example, the number 1,000,000 is read as 1 million in words in the international system, whereas, it is read as 10 lakhs in the Indian place value system. In the international system, different periods are formed to read and write large numbers easily. As per the International numeration system, the comma is placed in a number after the hundreds place and then placed after every three digits. The place values in the international system are Ones, Tens, Hundreds, Thousands, Ten Thousand, Hundred Thousands, Millions, and so on.
 1 million = 1000 thousands
 1 billion = 1000 millions
For example, the number 7,456,123 is written or read in words as seven million four hundred fiftysix thousand one hundred twentythree in the international number system.
Rules to Write Number Names
There are certain rules that can be followed while writing the numbers in words. These rules are listed below in detail.
Rule 1: Understanding the place value system: The position of a number plays a very crucial role in writing a number in words. Let us understand how to differentiate between the place values based on the position of 1:
 1 = ones place
 10 = tens place
 100 = hundreds place
 1000 = thousands place
Rule 2: For numbers between 120 we can directly refer to the number names 1 to 20 chart to write their spellings. For example, the number name of 7 is seven, the number name of 15 is fifteen, and so on. After number 20 a generic series or pattern is followed.
Rule 3: The number names for multiples of 100 can be simply written by adding the word 'hundred' after the initial word. For example, the number name of 400 is four hundred, the number name for 500 is five hundred, and so on.
Rule 4: To write the number names of more than 2 digit numbers, we write the number in its expanded form. For example, 112 = 100 + 12, and 112 in words is written as one hundred twelve. The expanded form of 153 = 100 + 50 + 3 and 153 in words is written as One hundred fiftythree.
Tips to Learn Number Names
The following tips can be kept in mind to write numbers in words:
 The number names from 1 to 10 can be written directly because each number name is unique, as 1 one, 2two, 3three, and so on.
 The number names from 11 to 20 can also be written directly because each number name is unique, as 11  eleven, 12twelve, and so on.
 The numbers and spellings of the multiples of 10 can be written as 20 twenty, 30 thirty, 40 forty, 50 fifty, 60 sixty, 70 seventy, 80 eighty, 90 ninety.
 Now, after 20, starting from 21, we follow a different rule. The word form of 20 and 1 can be combined to write 21 as twentyone, 22 as twentytwo, and so on. Similarly, we can write number names for 31, 41, 51, and so on.
 For large numbers write the number and their word form, like 100  hundred, 1000  thousand, and so on.
 The number 101 in words is written as one hundred one and 1001 is written as one thousand one and so on.
