What are the Units of Temperature?

  • Temperature is a way to measure how hot or cold something is.
  • We use special names called units to show temperature.
  • Some common units are Celsius, Fahrenheit, and Kelvin.
Examples:
  • Celsius:
    • In many countries, we often use Celsius for weather, like when we say it's 20C outside.
    • This unit helps us understand if we need a jacket or can go out in a t-shirt.

  • Fahrenheit:
    • In the US, people often use Fahrenheit, like when it's 68F on a sunny day.
    • This unit helps us decide if we can play outside comfortably.

  • Kelvin:
    • Scientists use Kelvin for very cold or very hot things, like when studying stars.
    • In this unit, an interesting number is 273 K, which is freezing!
