2. Scale of temperature - Wikipedia

   en.wikipedia.org/wiki/Scale_of_temperature

   Scale of temperature is a methodology of calibrating the physical quantity temperature in metrology. Empirical scales measure temperature in relation to convenient and stable parameters or reference points , such as the freezing and boiling point of water .

3. Temperature measurement - Wikipedia

   en.wikipedia.org/wiki/Temperature_measurement

   A medical/clinical thermometer showing the temperature of 38.7 °C (101.7 °F) Temperature measurement (also known as thermometry) describes the process of measuring a current temperature for immediate or later evaluation. Datasets consisting of repeated standardized measurements can be used to assess temperature trends.

4. Thermodynamic instruments - Wikipedia

   A meter does not perform its task accurately if it behaves like a reservoir of the state variable it is trying to measure. If, for example, a thermometer, were to act as a temperature reservoir it would alter the temperature of the system being measured, and the reading would be incorrect.

5. Wedgwood scale - Wikipedia

   en.wikipedia.org/wiki/Wedgwood_scale

   The origin on the Wedgwood scale (0 °W) was set at the onset temperature of red heat, 1,077.5 °F (580.8 °C). The scale had 240 steps of 130 °F (72 °C) and extended up to 32,277 °F (17,914 °C). [8] [11] Wedgwood tried to compare his scale with other scales by measuring the expansion of silver as a function of

6. Thermometer - Wikipedia

   en.wikipedia.org/wiki/Thermometer

   Separated columns are often a problem in both alcohol and mercury thermometers, and they can make a temperature reading inaccurate. The precision or resolution of a thermometer is simply to what fraction of a degree it is possible to make a reading. For high temperature work it may only be possible to measure to the nearest 10 °C or more.

7. Conversion of scales of temperature - Wikipedia

   en.wikipedia.org/wiki/Conversion_of_scales_of...

   This is a collection of temperature conversion formulas and comparisons among eight different temperature scales, several of which have long been obsolete.. Temperatures on scales that either do not share a numeric zero or are nonlinearly related cannot correctly be mathematically equated (related using the symbol =), and thus temperatures on different scales are more correctly described as ...
