Temperature measurement is the process of determining how hot or cold something is. This is done using instruments called thermometers, which can be found in various forms, such as digital or mercury-based. The temperature is usually measured in degrees, using scales like Celsius or Fahrenheit. Accurate temperature measurement is important in many fields, including weather forecasting, cooking, and medicine. For example, knowing the right temperature can help ensure food is cooked safely or that a patient has a normal body temperature. Understanding temperature helps us make informed decisions in our daily lives.
