Please consider helping us with an online survey which is part of an academic research project. The survey should not take longer than 10 minutes.
The diameter of the earth at the equator is 12,756 kilometers. That's not an easy number to remember but If someone asked you what the approximate distance was could probably remember that it's about 13,000 kilometers. You'd get that number by rounding to the nearest thousand. Below are two other examples showing rounding to the nearest thousand.
Note: You can use this rounding calculator at the foot of this page to round a number to the nearest 1,000.
Look at the number in the hundred's place and...

Let’s round a number to the nearest 1000.

3,777  23,698  43,459  268 
Underline the hundred's place.

3,777  23,698  43,459  268 
If it is less than 5, round down.

43,000  0  
If it is 5 or more, round up.

4,000  24,000
