How to Round the Decimal Number to the Nearest Thousandth?
To round off a decimal number to the nearest thousandth, we need to remember the following rules:
Case 1: If the 4^{th} digit after the decimal point is greater than or equal to 5, then while rounding off, we need to add 1 in the digit that is at the thousandth (3^{rd}) place after the decimal point.
Case 2: If the 4^{th} digit after the decimal point is less than 5, then while rounding off, we need to keep the thousandth (3^{rd}) place digit as it is.
For example, when we round off 35.64387 to the nearest thousandths, it gives us 35.644
This is because the 4^{th} digit after the decimal point is greater than 5. So while rounding off, we add 1 to the digit that is at the thousandth (3^{rd}) place after the decimal point.

Solved Example 1:
Round off the number 5.2476 to the nearest thousandth.
Solution:
The 4^{th} digit after the decimal point of the number 5.2476 is 6
The number 6 is greater than 5, so, we will add 1 in the digit that is at the thousandth (3^{rd}) place after the decimal point.
5.2476 ⇒ 5.248
Therefore, the number 5.2476 rounds to the nearest thousandth and becomes 5.248

Solved Example 2:
Round off the number 50.34826 to the nearest thousandth.
Solution:
The 4^{th} digit after the decimal point of the number 50.34826 is 2
Now as the number 2 is less than 5, so, we will keep the thousandth (3^{rd}) place digit as it is.
50.34826 ⇒ 50.348
Therefore, the number 50.34826 rounds to the nearest thousandth as 50.348
Now, you can use the calculator and round the decimal numbers to the nearest thousandth.
