目前使用的溫標(biāo)主要有攝氏溫度(Celsius temperature，記號t，單位℃)、熱力學(xué)溫度(Thermodynamic temperature，記號T，單位K)、華氏溫度(Fahrenheit temperature，記號tF，單位℉)、蘭氏溫度(Rankine temperature，記號TR，單位°R)和雷氏溫度(Réaumur temperature，記號tRé，單位°Ré)，它們的相互換算關(guān)系如下：
a℃ =(4/5) a °Ré = [ (9/5) a +32] ℉
b °Ré = (5/4) b ℃ = [ (9/4) b + 32] ℉
c ℉ = (5/9)(c - 32)℃ = (4/9) (c - 32)°Ré
d ℃ = (d + 273.15) K
e K = (e - 273.15)℃ = [1.80×(e - 273.15) + 32]℉= (9/5) e °R

攝氏溫度與華氏溫度的最典型的換算式是：
5（x ºF- 50）=9(yºC-10)
其中x代表華氏溫度的值，y代表攝氏溫度的值。
