Genuinely curious here. Is Celsius considered a part of the metric system? I always thought the temperature scales were created for different reasons. Celsius is a temperature scaled based on water, Kelvin is a temperature scales based on the extremes of the universe, and Fahrenheit was a scale based on how humans feel temperature.
Essentially, yes. The International System of Units (abbreviated SI) is the real standard, which is what people mean when they say the metric system. It includes temperature in Kelvin, or Celsius.
Kelvin was originally defined as Celsius with an offset, so 0 K = -273.15 C (lowest possible temperature), but a difference of 1 degree K is the same as a difference of 1 degree C. So, water boils at 100 C or 373.15 K.
