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
Suriname 29 to 34 degrees Celsius (84 to 93 degrees Fahrenheit). Due to the high humidity, actual temperatures are distorted and may therefore feel up to 6 degrees Celsius (11 degrees Fahrenheit) hotter than the recorded temperature. The year has two wet seasons, from April to August and from November to February. It also has two dry seasons, from August to November and February to April. Located in the upper Coppename River watershed, the Central Suriname Nature Reserve has been designated a UNESCO World Heritage Site for its unspoiled forests and biodiversity. There are many national parks in the country including
