Fahrenheit reference points became popular following the work of Anders Celsius and these fixed points were adopted by a committee of the Royal Society led by Henry Cavendish in 1776. Under this system, the Fahrenheit scale is redefined slightly so that the freezing point of water is exactly 32 °F, and the boiling point is exactly 212 °F or 180 degrees higher. It is for this reason that normal human body temperature is approximately 98° (oral temperature) on the revised scale (whereas it was 90° on Fahrenheit's multiplication of Rømer, and 96° on his original scale). The Rankine temperature scale was

In St. Petersburg, various temperature records were broken in July, and the maximum yearly temperature record was set on Wednesday, 28 July, when the temperature was 35.3 degrees Celsius (95.5 degrees Fahrenheit). This record was superseded on 7 August — 37.1 degrees Celsius (98.8 degrees Fahrenheit).
