🎯 Round to the Nearest Tenth Calculator
The nearest tenth is one digit after the decimal point. Look at the hundredths digit: 5 or more rounds the tenths digit up, 4 or less leaves it. So 3.46 becomes 3.5 while 3.44 stays 3.4 — the precision used for grades, ratings and measurements.
Enter any decimal and the calculator rounds it to a single decimal place, displaying the result exactly as written, trailing zero included.

Frequently asked questions
What is rounding to the nearest tenth?
Keeping one digit after the decimal point. The hundredths digit decides: 5 or more rounds the tenths digit up, so 3.46 becomes 3.5.
Why does the calculator show 3.0 instead of 3?
The 'as written' row keeps the trailing zero to show the precision: 3.0 tells the reader the value was rounded to tenths, not to a whole number.
Where is tenth precision used?
School grades, product ratings, race times and lab measurements commonly keep one decimal place.
What about 2.75?
It becomes 2.8. A hundredths digit of 5 rounds the tenths digit up under half-up rounding.
