what is the most important number on the thermometer
This would depend upon exactly why you are taking the temperature. Is it to tell if a person is ill? Is it to tell if food is cool enough to not decompose? Is it to tell the weather forecast?

what is the most important number on the scale(regarding a thermometer that shows the temperature to tell the weather forecast)
The most important number on a thermometer depends on the purpose for which it is being used. Different applications may require different temperature ranges to be measured accurately.
For general purposes, the most commonly used and important number on a thermometer is the boiling point of water, which is 100 degrees Celsius or 212 degrees Fahrenheit at sea level under normal atmospheric conditions. This temperature is significant because it defines the upper limit of the temperature scale for many everyday activities like cooking, heating, and weather reporting.
To get this value or any other value on a thermometer, you would typically follow these steps:
1. Read the thermometer scale: Look for the markings or numerals on the thermometer to determine the unit of measurement (Celsius or Fahrenheit) and the division (degree increments).
2. Observe the level of the liquid or the position of the mercury: Thermometers may operate using various principles, such as liquid expansion (alcohol or mercury) or electronic sensors. Check the level of the liquid or the position of the mercury within the thermometer's tube.
3. Identify the desired temperature: To find the most important number (e.g., boiling point of water), locate the corresponding temperature on the scale. For Celsius, it will be 100°C, while for Fahrenheit, it will be 212°F.
By understanding the scale and markings on the thermometer, you can find the desired temperature accurately. Keep in mind that different types of thermometers may have different scales and markings, so it's important to familiarize yourself with the specific thermometer you are using.
