Round any number to the nearest hundred.
How it works
The value is divided by 100, rounded to the nearest whole number using the standard “round half up” rule, then multiplied back by 100. 549 rounds down to 500; 550 rounds up to 600.
What this does not include
This rounds specifically to the nearest hundred. For a different magnitude, see this site’s other rounding calculators — round to the nearest tenth, hundredth, or thousand each handle a different scale.
How to use this calculator
- Enter a number.
What happens to a number exactly halfway between two hundreds?
It rounds up — 550 becomes 600, following the standard “round half up” convention used throughout this site’s rounding calculators.
Does this work for negative numbers?
Yes — a negative number rounds to the nearest hundred the same way, so −549 rounds to −500.
Why would I round to the nearest hundred instead of an exact figure?
Rounded figures are easier to communicate and remember in reports, estimates, and headline numbers, where exact precision would be misleading anyway given the underlying uncertainty.
