چکیده
Measurement in science has a long tradition as described by Lemmerich /LEMM88/. While the measurement of length the meter was defined in 1889 /LEMM88/, p.87, the measurement of temperature was more complicated. The graduation of the distance of the fixpoints was introduced by Fahrenheit in 1714 and by Celsius in 1742. Celsius devided the scale of 100 degrees and 0 degrees in hundred equal sectors. But the question was for a long time whether 50C was uniquely defined. Another interesting case is that the measurement of length is always a ratio scale, but temperature can be both an interval (Celsius / Fahrenheit) or a ratio scale (Kelvin).
