Put it in a pot of water. Boil the water. Then mark the spot on the thermometer at which the water boils - the spot you marked will be 100 degrees celsius. Then put it in water in the freezer and mark it. The point at which the water freezes will be 0 degrees celsius. Then measure the length between 0 and 100 and make 9 equal marks for each 10 degrees and your thermometer is calibrated.

To calibrate a Celsius temperature scale locally, you can use a reliable reference point, such as the freezing point of water (0°C) and the boiling point of water (100°C) at sea level. First, ensure that your thermometer is accurate by placing it in ice water to verify it reads 0°C, then check it in boiling water to confirm it reads 100°C. If adjustments are needed, you can either recalibrate it according to the deviations observed or use a calibration software if your device supports it. Finally, document any changes made for future reference.
Temperature scale used on most laboratory thermometers is a thermometer.
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.
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 two main lines on a thermometer are the freezing point (32°F or 0°C) and the boiling point (212°F or 100°C) of water. These lines help calibrate the temperature scale.
To calibrate a stem thermometer, it must have a clear and accurate scale, ideally marked in both Celsius and Fahrenheit. It should be immersed in a reference substance, such as ice water or boiling water, to check its accuracy against known temperature points. Adjustments can then be made if the readings deviate from the expected values. Regular calibration ensures reliable measurements in various applications.
Unfortunately, without a calibration weight, it can be challenging to calibrate a digital pocket scale accurately. One option could be to try using a known weight object, like a coin with a verified weight, to help calibrate the scale. However, for best results, it is recommended to use a proper calibration weight designed for that specific scale model.
There is nothing special about either scale
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.
I calibrated the scale so I could weight myself
In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature.
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.

A thermometer measures temperature by using a substance that expands or contracts with temperature changes, such as mercury or alcohol. As the substance heats up or cools down, it moves along a scale marked on the thermometer, providing a reading of the temperature.
