How to measure the temperature?

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

1. Measured with a thermometer, the percentage system is generally adopted. Under standard air pressure, the boiling point of water is set to 100℃, the temperature of ice-water mixture is set to 0℃, and the middle is divided into 100 equal parts, each equal part represents 1℃.

2. temperature measuring gun is used to measure the body temperature by measuring the molecular movement in the air.

3. Hang the thermometer in a fixed position, the sensing part of the thermometer is about 1.5m from the ground, and the ventilation condition is good, which makes the measurement result more accurate.

4. put the thermometer in the louver to measure. The louver box is 5 meters away from the ground 1.5 meters, with good ventilation and no direct sunlight. The ground is a lawn, so the measured temperature can eliminate the influence of external factors and ensure the accuracy of the measured value.

It should be noted that when using a thermometer to measure temperature, you should follow the instructions correctly to avoid mistakes.
