To celsius converter

It is most commonly used in the United States in weather forecasts and to describe temperatures inside houses, offices, etc. I asked a few people and the conversion formula is the first thing that comes to mind - and how hard it is to remember.

The result won't be accurate but it does provide an approximate number that's "good enough" in everyday situations. Note: For a pure decimal result please select 'decimal' from the options above the result. There's a simple rule to convert Fahrenheit to Celsius that should be good enough for general use.

Simply take 30 off the Fahrenheit value, and then half that number. In the Fahrenheit scale, water freezes at 32 degrees, and boils at degrees. Boiling and freezing point are therefore degrees apart. Normal body temperature is considered to be Absolute zero is defined as The Celsius scale is nowadays set in such a way that Zero degrees C is the temperature at which ice melts note : not the temperature at which it freezes, which is different!

At the other end of the scale, degrees Celsius is the boiling point of water. Celsius as a unit and a scale was not widely used until this original definition was inverted.

In , the unit, "degree Celsius," as well as the Celsius scale were again re-defined to instead be based on absolute zero This is the definition that was used up until , when the kelvin was redefined based on the definitions of the second, meter, and kilogram. Current use: The Celsius scale replaced the Fahrenheit scale in most countries in the mid to late 20 th century. Almost all countries around the world use this scale, except for those in which the metric system has not been adopted, such as the United States.
