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
Hot container composting bark takes several months. Hot container composters aim for a temperature range of between 100 degrees Fahrenheit (43 degrees Celsius) and 140 degrees Fahrenheit (60 degrees Celsius) to aid optimal bacterial decomposition. A suitable thermometer, analogue or digital, is needed for monitoring this. If you don't have a thermometer, you have to wait for the final product to inspect if it is suitable. The bottom door is only opened to extract the compost when the top is full. The first time you open the door, there will be partially decomposed material. This is due to the most of the decomposition
