Gabriel Fahrenheit created another scale in the 18th century, which was smaller but remained impractical for measuring temperature.

The first scale similar to the modern era is created by the English scientist Sir Thomas Clifford Allbutt in 1876.

For the first time, the work of this measure relied on the use of mercury and compared its expansion to body temperature, and was about 15 cm long...

The thermometer was based on the scientific fact that the physical properties of materials change with temperature changes, such as the expansion of the liquid with its high temperature and its shrinking fluid with low temperature...
