International medical research and pharmaceutical storage requirements rely on Celsius for precision.

Pilots and meteorologists worldwide use Celsius to report engine temperatures and icing conditions.

The Kelvin scale is the SI base unit for temperature. It uses the same degree increments as Celsius, but it starts at (the point where all molecular motion stops).

Fahrenheit is often praised for being more "human-centric" for weather (0°F is very cold, 100°F is very hot). Celsius, however, is considered more "science-centric" because of its clear alignment with the physical states of water.
