Fahrenheit to Celsius
Convert Fahrenheit to Celsius. Type either box. No ads when the number changes.
The number stays in this tab
This URL is fahrenheit to celsius, not a category picker. You landed here because that is the pair you typed. 350 °F is 176.667 °C. Both boxes update as you type. Copy puts the answer on the clipboard, nothing else.
I built these pages because a converter I opened to turn 350 F into Celsius put a video in front of the next change. The named complaint about converter apps is an ad that fires when you change a unit. There is no ad slot on this page. Change the number, read the other box.
The conversion runs in JavaScript here. Mixpanel and Google Analytics load with Softery.io. They see that someone opened this pair. They do not get the number you typed. After the page has loaded you can unplug the cable and still convert.
The formula for this pair
C = (F minus 32) × 5/9
Fahrenheit go in the left box. Celsius come out of the right box. Type either side. The page uses the international definition for this pair, not a rounded classroom figure that drifts when you convert back.
The reverse lives at Celsius to Fahrenheit. Swap is that link with the current answer already filled in. Add ?v= plus a number to this address if you want someone to land on the same figure.
A chart you can copy
The table above the fold is ordinary text. Select a row and paste it into a sheet. It is not a picture, so a screen reader can read it and a colleague can reuse it.
The values are the ones people actually ask for on this pair. If your number is not on the list, type it. The boxes are the source of truth. The chart is a shortcut for the common ones.
Gallons and fluid ounces on this site are US units. The pound is avoirdupois. The inch is 2.54 centimeters exactly. If you needed the imperial gallon, this page will not pretend it is the same number.
Nearby pairs
Same engine, different URL. The hub at Unit Converter lists every pair. I wrote why the other converters put an ad on a unit change on the blog.
Nearby tools that also stay in the tab: the word counter, the password generator, and the wheel spinner.
Common questions
What is 350 F in Celsius?
350 °F is 176.667 °C. That is (350 minus 32) times 5/9. The page uses that identity, so an oven setting of 350 lands on the same number every time.
Do you show an ad when I change the number?
No. Change the number, read the other box. Nothing sits between those two fields. The page is free because the arithmetic costs nothing to run.
Does the number I type leave this tab?
The conversion runs in this tab. Mixpanel and Google Analytics load with Softery.io. They see that someone opened the page. They do not get the number you typed.
Can I send this conversion to someone?
Yes. Add ?v=350 to this address. They land on the same pair with that number already filled in.
