25 degrees is not called room temperature, but Sandard Reference Ambient temperature. All measurements of any components or equipment is dependent on the temperature and atmospheric pressure at the place of measurement (STP). Values of resistance/ capacitance/ inductance vary with temperature.

To bring about uniformity in measurements anywhere anytime in the world, it has been internationally decided to refer 25 degrees Celsius as the standard reference temperature, and any measurement at a different ambient temperature has to be corrected to give value at this standard temperature.

Most laboratories keep the room temperature as close as possible to this , and standard practices require laboratory to have temperature between 23 and 27 degrees Celsius. In case of very precision measurement, correction is still done for 25 degrees.

In fact, in many measurements, even the earth gravity is standardized as being at one specific point on earth, since gravitational field is different at different places.
