Fahrenheit temperature scale, developed in 1724 by Gabriel Daniel Fahrenheit, is based on 32 for the freezing point and 212 for the boiling point of water (Three Big Temperature Scales, n.d.). The interval between freezing point and boiling point is divided in 180 equal parts. The absolute zero for the Fahrenheit temperature scale is at -459.67 °F. It is a non-metric temperature scale. Meteorologists in the United States use it to record surface temperature measurements. Medical practitioners use it to record human body temperature. Celsius temperature scale, invented in 1742 by the Swedish astronomer Anders Celsius, is the modern system of measuring temperature and is based on 0 for the freezing point and 100 for the boiling point of water. The interval between freezing point and boiling point is divided in 100 equal parts. The absolute zero for the Celsius temperature scale is at -273.15 °C. It is a metric temperature scale. Both Fahrenheit and Celsius are used to record weather temperatures.
