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
Australian Grains Genebank order to keep the seeds safe, they are stored in 2.7 kilometres of shelf space at -20 degrees Celsius (-4 degrees Fahrenheit) with very low moisture. The seeds can remain viable for 50 or 100 years (depending on the kind of seed), preserving, in this way, the genetic materials. The primary reason for the bank to be created was the extreme temperatures in the area, up to 40 degrees Celsius (104 degrees Fahrenheit) in the summertime. Because of that, they had to ensure the protection of the grains all year around. The longevity of seeds differs; some keep well for
