The result of your conversion between Reaumur and Celsius appears here
To convert between Reaumur and Celsius you have to do the following:
First divide 3 / 0 = 3.
Then multiply the amount of Reaumur you want to convert to Celsius, use the chart below to guide you.
Description: Temperature scale that takes 0 (0 ° R) as the freezing point of water and 80°R as the boiling point of the same under normal pressure. This range is divided into 80 equal parts (degrees Reaumur).
Description: To establish a baseline temperature measurement, Anders Celsius used (in 1742) melting points and boiling water. It is considered that a mixture of ice and water which is in equilibrium with saturated air at 1 atm is in the melting point. A mixture of water and water vapor (without air) at equilibrium at 1 atm pressure is considered to be the boiling point. Divided Celsius temperature interval between these two points into 100 equal parts that were called degrees Celsius ° C. However, in 1948, were renamed in his honor degrees Celsius, likewise began to use the letter to call them.
In 1954 the Celsius scale was redefined at the Tenth Conference of Weights and Measures in terms of a single fixed point and the absolute temperature of absolute zero. The point chosen was the triple point of water is the state in which the three phases coexist in equilibrium water, which was assigned a value of 0.01 ° C. The magnitude of the new degree Celsius is defined as absolute zero as the fraction 1/273, 16 the temperature range between the triple point of water and absolute zero. As the new scale in the melting and boiling points of water are 0.00 ° C and 100.00 ° C respectively, the scale is identical to the above definition, with the advantage of having a thermodynamic definition.
