The thermometer double scale how to calculate the temperature

Temperature units with symbol refers to c & quot; ° C' Said people use a thermometer to measure temperature. Under a standard atmosphere, the ice water temperature at zero, the boiling water temperature was 100 degrees, among them into 100 equal pieces, each equal parts is a unit of degrees Celsius, called one degree Celsius. ” The Fahrenheit scale & quot; Experience is one of the scale. Daily life in the United States, we adopt this kind of scale. Stipulation in atmospheric pressure the freezing point of water is 32 degrees, the boiling point is 212 degrees, is divided into 180 equal between two standard points, each equal 1 degree. Fahrenheit letters & quot; F” Said. Celsius ( ℃) And Fahrenheit ( ℉) The conversion relationship between the: F = 9 ℃ / 5 + 32, or 5 ℃ = ( F - 32) / 9 c & times; 9/5 + = 32 degrees Fahrenheit. Thermometer usually two scale: c ( Remember to 0 ℃) And Fahrenheit ( Remember to 0 ℉) 。 Fahrenheit and Celsius into rate: f = 32 + c & times; 1. 8 degrees Celsius = ( Degrees Fahrenheit - 32) ÷ 1. 8 bimetallic thermometer can be directly measured in the process of various production - 80 ℃ ~ + 500 ℃ within the scope of liquid, steam and gas medium temperature. Table card can also have two scale: c ( Remember to 0 ℃) And Fahrenheit ( Remember to 0 ℉) 。
