Temperature Scales and Conversions Explained

This video from Two Minute Classroom explains the three main temperature scales: Celsius, Fahrenheit, and Kelvin. It covers the freezing and boiling points of water on each scale and introduces the concept of absolute zero. The video provides step-by-step instructions for converting between Celsius and Kelvin, as well as Celsius and Fahrenheit, using simple equations. Viewers are encouraged to engage with the content by asking questions and watching additional videos.
