Fahrenheit He then re-calibrated his scale using the melting point of ice and normal human body temperature (which were at 30 and 90 degrees); he adjusted the scale so that the melting point of ice would be 32 degrees and body temperature 96 degrees, so that 64 intervals would separate the two, allowing him to mark degree lines on his instruments by simply bisecting the interval six times (since 64 is 2 to the sixth power). Fahrenheit observed that water boils at about 212 degrees using this scale. The use of the freezing and boiling points of water as thermometer fixed
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
