The bimetallic thermometer the Fahrenheit scale

Instrumentation products including on-site instructions and control instrument, temperature, pressure, humidity, air pressure series, all kinds of different industries to provide the high quality for more than 30 countries thermometer and pressure gauge products, technical support and professional services, over more than 500 models of specific products, widely used in industry, agriculture, science and technology, medical, office, family, daily provisions, gifts and other fields. The instrument as the main products of the bimetallic thermometer, use scale besides degrees Celsius and Fahrenheit. Fahrenheit units for ℉, is set by the 1724 German warren hite, he has made a certain concentration of the temperature of the salt water freezes at 0 ℉, 32 ℉, freezing point temperature of the water as a standard atmospheric pressure, the boiling point of water temperature at 212 ℉, middle is divided into 180 equal parts, each equal parts represent 1 degree, this is the Fahrenheit scale, using symbols F says, this is Fahrenheit. Celsius temperature freezing point temperature of 0 degrees Celsius, the boiling point of 100 degrees Celsius, so one degree Celsius ( 1 equal parts) Is equal to 9/5 degrees Fahrenheit and Celsius and Fahrenheit temperature change formula is: ℃ = 5 & times; ( ℉- 32) / 9日℉= 9报; ℃ /5+32。 Fahrenheit has the advantage of every degree temperature difference is small, in the case of all rounded, more accurate than c, and Fahrenheit in expressing the common temperature can also avoid the occurrence of negative; C is the advantages of convenient and scientific computing.
