Convert Fahrenheit to Celsius & Other Temperatures on the iPhone with Siri

Mar 27, 2013 - 6 Comments

Siri logo Some countries use fahrenheit, others use celsius, and if you’re an alien on an unusually extreme planet maybe you even use kelvin… whatever the case we’ve all run into the situation where someone from elsewhere is referring to a temperature in a scale you’re unfamiliar with. Obviously if someone in the USA says “wow it was 10 degrees!” that means it’s really cold weather, but if a native German said the same thing, that’s quite mild weather. Rather than trying to do the funky math in your head, just ask Siri. No, she won’t report the weather back directly in another temperature scale (we’ll cover that through a Settings adjustment, however), but she will perform temperature conversions from celsius to fahrenheit and vice versa.

Convert Temperatures on the iPhone with Siri

Try the following phrases:

  • “What is [temperature] [scale] in [scale]?”
  • “Convert [temperature] degrees [format] to degrees [format]”
  • “What is 10 degrees celsius in fahrenheit?”
  • “What is 75 degrees fahrenheit in celsius?”
  • “Convert 25 degrees celsius to degrees fahrenheit”

You get the idea. Siri will quickly give you an answer under “Result”.

If you look under the “Additional conversions” section, you’ll find Siri has also provided the temperature converted into other scientific formats too, like kelvins and Rankine.

Set Siri to Report Temperature in Celsius or Fahrenheit

Visiting another country and want to use their temperature format? Or maybe you’re just trying to learn another scale? You can get Siri to give you the weather in celsius (centigrade) or fahrenheit by changing a simple setting:

  • Open the “Weather” app and tap the (i) button in the corner
  • Choose either “F” or “C”

Now ask Siri the weather again, it will be reported back whichever you chose, farhenheit or celsius, depending on the settings in Weather app.

At this point, you can’t ask Siri directly for the current temperature of a location in another format, but by switching the setting in Weather you will end up with the same effect.

    This is THE most helpful SIRI advice on temparature setting. I have gone through so many forums. Thank you.

    Only Liberia and Burma use Fahrenheit officially. Celsius, is officially the standard in the United States, but since Americans like to “phase things in” (which means “never switch”), Fahrenheit is still in use in everyday life.

    The US National Institutes of Science and Technology defines the mile, yard, foot, inch, both kinds of ounces, pound, and Fahrenheit in terms of the international standard (“metric system.”)

    Many people have never heard of a Fahrenheit and don’t know what it is. I understand that some people still use Réaumur in Belgium, so the USA isn’t the only country that is a slave to tradition.
