Temperature is a measure of how hot or cold an object is. It can be measured using a thermometer, which tells you the temperature in degrees Celsius. Most thermometers only measure temperatures up to 100°C, but some can measure higher temperatures. Water freezes at 0°Celsius (or 32°Fahrenheit) and boils at 100°Celsius (212°Fahrenheit). The highest ever recorded temperature on Earth was 57.8 °C in the Lut Desert in Iran, in 2005. The lowest temperature ever recorded was -89.2 °C, which happened twice in Antarctica, first in 1983 and again in 2013. Temperature is a measure of how hot or cold an object is. It is measured using a thermometer. Temperature is a measure of how hot or cold an object is. It is measured using a thermometer. The temperature scale used in the United States and other countries is called Celsius (°C). The Celsius scale was created by a Swedish astronomer named Anders Celsius in 1742; however, it was revised by another Swedish astronomer named Gabriel Daniel Fahrenheit in 1724. The temperature can be measured in Celsius and Fahrenheit. The temperature can be measured in Celsius and Fahrenheit. Celsius is more commonly used than Fahrenheit, but it’s also more accurate. The units are the same as millimeters and inches—the difference lies in the scale. For example: 100 mm = 39 inches 0.39 meters = 1 foot Celsius and Fahrenheit are equal at -40 degrees. The Celsius and Fahrenheit scales are equal at -40 degrees. We use the same scale for Celsius as for Fahrenheit, but we multiply by 9/5 to convert from Celsius to Fahrenheit: For example, if you want to convert 20 degrees C to Fahrenheit, you would get 40 (20×9/5). If you want to convert -10 degrees F into Celsius, you would get -20 (9/(-5)) Most thermometers only measure temperatures up to 100°C, but some can measure higher temperatures. Thermocouples are used in many industries, including: Industrial manufacturing Automotive and aerospace industries. They are also used to measure high temperatures (up to 2000°C). Water freezes at 0°Celsius (or 32°Fahrenheit) and boils at 100°Celsius (212°Fahrenheit). When we talk about the temperature of something, we are referring to the average kinetic energy of its particles. If you have heard of “heat,” this is what that term refers to: the amount of energy in a substance. The more heat in a substance, the higher its temperature will be. Temperature is measured in degrees Celsius (°C) and Kelvin (K). Water freezes at 0°Celsius and boils at 100°Celsius; it does not freeze or boil at any other temperatures than these two numbers. For example, when water reaches 100°Celsius, this means there is around 200 joules per kilogram of water present—this is known as its specific heat capacity or enthalpy_.

The average temperature of Earth is 15 degrees Celsius (https://www.wielerflits.nl/wielerforum/users/pikniki/). That’s not to say that there isn’t variation from place to place; it just means that you shouldn’t expect your climate to be drastically different from the global average—unless you live near a volcano or something! Temperature is a really important concept Temperature is a really important concept to understand. It’s one of the most commonly used measurements in science and everyday life, and it’s extremely useful for keeping you healthy. In this lesson, we’ll learn about what temperature is, how it works and why it’s important for you to know about it. What is temperature? Temperature is a measure of how hot or cold something is. You can measure the temperature using a thermometer or other devices that can measure heat (e.g., your skin).
