How to measure the temperature?

There are many ways to measure temperature, common ones include:

1. Use a thermometer to measure, and thermometers generally use the Celsius unit system. Under standard atmospheric pressure, the boiling point of water is set as 100°C, the temperature of the ice-water mixture is set as 0°C, and the mixture is divided into 100 equal parts, each equal part representing 1°C.

2. Use a temperature gun to measure body temperature by measuring the movement of molecules in the air.

3. Hang the thermometer at a fixed location. The location should be such that the sensing part of the thermometer is about 1.5 meters away from the ground, and the ventilation conditions are good to make the measurement results more accurate.

4. Place the thermometer in a shutter box for measurement. The shutter box is 1.5 meters above the ground. It is well ventilated and is not blocked by direct sunlight or other objects. The ground is covered with lawn, so the measured temperature can be eliminated. influence of external factors to ensure the accuracy of measurement values.

It should be noted that when using a thermometer to measure the temperature, you should follow the instructions for use and operate it correctly to avoid errors.
