When we are dealing with financial reports, population statistics, or global economic data, they are filled with endless zeros (i.e, 1,000,000,0), then face difficulties in understanding data. These endless zeros make reports or numbers difficult to read and understand.
To understand these numbers, we need to learn unit conversion that helps to convert large numbers in a readable manner, like millions & billions. Presenting big numbers in this format helps to make better decisions by making financial reports on population statistics and global economic data. It also improves the overall quality and accuracy of data, building trust for clients or stakeholders.
In this post, you’ll learn effective methods for converting large numbers into millions and billions. But, before we begin converting numbers, it’s important to understand what are million and billion.
What is Million?
Millions is a number equal to 1,000,000 or one thousand thousand. It’s a large quantity often used to describe numerous or substantial amounts. The word million comes from the Italian word “milione” (meaning one thousand).
| Important note:
Some countries (i.e., Europe) use the “long scale” (Where 1 billion = 1 million million). But in the United States and most other English-speaking countries, we use the “short scale”. This is the system we will use in this blog. |
Let’s now understand the conversion process of big numbers into millions.
How to Convert Big Numbers into Millions?
To convert big numbers into millions, you’ll need to follow the steps below:
- Identify the number that you want to convert.
- Understand the value of one million. It is written as 1,000,000.
- Apply the formula. It depends on the conversion unit.
Some important formulas are given below for different conversions in millions with examples:
| Unit | Formula to Convert to Millions | Example (1 unit) |
| Hundred | Value ÷ 10,000 | 1 hundred = 0.0001 Million |
| Thousand | Value ÷ 1,000 | 1 thousand = 0.001 Million |
| Lakh | Value ÷ 10 | 1 Lakh = 0.1 Million |
| Crore | Value × 10 | 1 Crore = 10 Million |
| Billion | Value × 1,000 | 1 Billion = 1,000 Million |
| Arab | Value × 100 | 1 Arab = 100 Million |
| Kharab | Value × 10,000 | 1 Kharab = 10,000 Million |
| Trillion | Value × 1,000,000 | 1 Trillion = 1,000,000 Million |
| Rupees | Value ÷ 1,000,000 | 1 Rupee = 0.000001 Million |
Example:
Convert the number 7,850,000 into Millions.
Conversion:
We want to convert 7,850,000 into millions. So, let’s apply the formula to this:
Number in Millions = 7,850,000 / 1,000,000 = 7.85
7.85 means “seven point eight five million.”
Alternative Method (Moving the Decimal):
This method is conceptually the same as division, but can be quicker for mental calculations.
- Identify the number: (e.g., 94,500,000)
- Locate the implicit decimal point: For whole numbers (e.g., 94,500,000).
- Move the decimal point 6 places to the left: Since a million has 6 zeros, moving the decimal 6 places to the left is equivalent to dividing by 1,000,000.
(Start)
94,500,000.
9,450,000.0
945,000.00
94,500.000
9,450.0000
945.00000
94.500000 (Here 6 places are done)
So, 94,500,000 becomes 94.5 million.
What is Billion?
A billion is a numerical value representing one thousand million. It can be mathematically written as 1,000,000,000 and in scientific notation 109. It has 9 zeros. “B” is the most usable word to represent a billion.
How to Convert Large Numbers into Billions
For the conversion of large numbers into billions, there is no general formula. Each unit has its own way of conversion. Some important unit conversions in billions are given below:
| Unit | Formula to Convert to Billions | Example (1 unit) |
| Hundred | Value ÷ 10,000,000 | 1 Hundred = 0.0000001 Billion |
| Thousand | Value ÷ 1,000,000 | 1 Thousand = 0.000001 Billion |
| Lakh | Value ÷ 100,000 | 1 Lakh = 0.00001 Billion |
| Million | Value ÷ 1,000 | 1 Million = 0.001 Billion |
| Crore | Value ÷ 100 | 1 Crore = 0.01 Billion |
| Arab | Value × 0.1 | 1 Arab = 0.1 Billion |
| Kharab | Value × 100 | 1 Kharab = 100 Billion |
| Trillion | Value × 1,000 | 1 Trillion = 1,000 Billion |
Example:
Convert the 1 Kharab into a billion.
Solution;
To convert the 1 Kharab into a billion, we use the following formula:
Number in Kharab * 100
1,00,00,00,00,000 * 10 = 100 billion
You can also use the decimal replacement method as an alternative for this conversion.
| Pro Tip:
If you’re still confused about converting large numbers into billions and millions, and worried about how to remember too many formulas of conversion. Then worry not, you can make this process easy by using online converters like number to million converter, which converts different big numbers into small units such as million, billion, crore, lakh, and many more. |
