Scale Lines

The scale is the series of lines that are etched into an area to the side of the capillary. The scale allows the temperature to be read off in units of degrees. The type of degree unit depends upon the specific thermometer. Two commonly used temperature scales, are degrees Celsius and degrees Fahrenheit, which are found on everyday thermometers. An alternative scale that measures temperature in degrees Kelvin is often used by scientists and engineers.
