The solubility depends on the temperature; and because 20 0C is considered a normal room temperature, this temperature is frequently used as a standard.
The temperature of 25 0C is rarely used but it is your choice, depending on the application, to consider any temperature.
The problem of standard conditions is not solved; different countries and organizations use similar but not identical temperatures and pressures as standards. The understanding between scientists involve a severe standardization in all fields to correct comparison of the results of experiments.
An aside:
20o C is considered more a physics standard temperature while 25o C is The IUPAC standard and is used in most chemistry experimental as the standard temperature.
68.00 degrees Fahrenheit
27 degrees could be written as of: 27%
24 degrees Celsius = 75.2 degrees Fahrenheit
25 degrees Celsius is 77 degrees Fahrenheit.
