The point at which water freezes and the point at which water boils.
Two reference temperature points are needed to create a thermometer scale. These points are used to calibrate the scale and typically consist of the freezing and boiling points of a substance, such as water.
The most accurate method for calibrating a bimetallic thermometer is to use a high-precision reference thermometer to compare and adjust the readings of the bimetallic thermometer at various temperatures. This process involves immersing both thermometers in a stable temperature source and recording the differences in readings to make necessary adjustments to the bimetallic thermometer's scale. Calibration should be performed at multiple points across the temperature range of interest to ensure accuracy.
To mark a temperature scale on a thermometer, you would need to calibrate it by comparing it to a known reference temperature. Then, you can make corresponding marks at various points on the thermometer scale to indicate different temperature readings. It's important to ensure accuracy and consistency during this process.
The index of a thermometer is the scale or numerical reference used to indicate temperature readings. It can be in either Celsius or Fahrenheit, depending on the type of thermometer.
To increase the linearity of a thermometer, you can calibrate it regularly using known reference points. This involves adjusting or correcting the scale readings to ensure they accurately reflect the temperature being measured. Additionally, using high-quality materials and components in the thermometer's construction can also help improve its linearity.
Daniel Fahrenheit developed his temperature scale by using a mercury-in-glass thermometer. He established reference points based on the freezing and boiling points of water, assigning 32°F to the freezing point and 212°F to the boiling point at standard atmospheric pressure. He then divided the interval between those points into 180 equal parts to create the Fahrenheit scale.

There is nothing special about either scale
Fill a container with crushed ice and water, stirring to ensure uniform temperature. Immerse the thermometer probe into the ice water for several minutes until the reading stabilizes. Adjust the thermometer's calibration screw or electronic settings until it reads 0°C or 32°F, depending on the scale used.
The least count of a thermometer scale is the smallest temperature difference that can be measured by the scale. It is typically based on the precision of the markings on the scale, which can vary depending on the design and calibration of the thermometer.
