what type of measurement scale is used for temperature
A perfect example of an interval scale is the Fahrenheit scale to measure temperature. The scale is made up of equal temperature units, so that the difference between 40 and 50 degrees Fahrenheit is equal to the difference between 50 and 60 degrees Fahrenheit.
Celsius used 0Â° for the boiling point of water and 100Â° for the melting point of snow. This was later inverted to put 0Â° on the cold end and 100Â° on the hot end, and in that form it gained widespread use. It was known simply as the centigrade scale until in 1948 the name was changed to the Celsius temperature scale.
