### What is Meant by Rounding to the Nearest Thousandth?

In Maths, the rounding of numbers means the trimming of numbers to the nearest place value. In the decimal number system, the numbers after the decimal points are defined as tenths (1/10), hundredths (1/100), thousandths (1/1000), and so on. Here, thousandth is a place, which is located at the third position after the decimal point. For example, 3.1678 is a decimal number. The thousandth digit of the given decimal number is 7.

To round any decimal number to its nearest thousandth, follow the steps given below:

Let 7.1239 is a decimal number. Now, we have to round the given decimal number to its nearest thousandth.

**Step 1:** Identity the thousandth digit. (Here, 3 is the digit which is in thousandth place)

**Step 2:** Now, look at the digit, which is next to the thousandth place. If that digit is less than 5, round down the thousandth digit. If that digit is greater than or equal to 5, round up the thousandth digit. From the example given above, the digit next to the thousandth digit (i.e., 9) is greater than 5, so we have to round up the thousandth digit.

**Step 3:** Thus, the number 7.1239 rounded to the nearest thousandth is 7.124.
