Rømer then saw that the freezing point of pure water was roughly one eighth of the way (about 7.5 degrees) between these two points, so he redefined the lower fixed point to be the freezing point of water at precisely 7.5 degrees. Rømer's temperature scale was based on the boiling point of water being 60 degrees - astronomers are used to dividing things by 60, seeing as space is divided up this way into arcminutes and seconds. Are you sure you want to cancel your membership with us? Newton's system was calibrated between the freezing point of water (0 degrees) and human body temperature (12 degrees); it was a coarser scale, but unlike Rømer's it was not intended for everyday use, as Newton's interest was in determining the boiling points of metals, which are not readily accessible with Rømer's system based on liquid thermometers. Alongside the Newton scale, it was the first calibrated scale. In Rømer’s scale, brine freezes at 0 degrees, ice melts at 7.5 degrees, body temperature is 22.5, and water boils at 60 degrees.
