Centrigrade, or Celsius: which is correct?
« on: 01/04/2012 10:35:01 »
Matt | Model Concepts  asked the Naked Scientists:
     
Hello Chris,

I've been listening to your podcasts for ages and always wanted to send in my questions.

Celcius v Centigrade: Your guests have used both. And many specialists just say "C". So, which is it?

Love your programme. You guys rock.

Be cool,
Matt

For the sake of passing exams; The GCSE and A-level specification requires not Celsius but 'degree Celsius'

Here are some historical notes.
http://chemistry.about.com/b/2012/01/24/difference-between-celsius-and-centigrade.htm

Apparently the original term was centigrade, for 100 degrees between freezing and boiling.

In 1948 when they changed the standards to be based on the triple point of water and absolute zero, the scale was renamed Celsius.  So, technically, Celsius would be the correct term now.

Just to confuse the issue, the Fahrenheit scale is also a centigrade scale.
The fixed points were the freezing point of the eutectic mixture of ice and salt (at about -18C) and body temperature (at about 37C).
Then they re-standardised the F scale to give 212 as the steam point which moved typical body temperature a bit away from 100.
