Absolute zero (-273.15°C or -459.67°F) is the lowest possible temperature where all atomic motion stops.
The Celsius scale was originally defined with 0° as the boiling point of water and 100° as the freezing point.
The surface of the Sun reaches about 5,778 K (5,505°C or 9,941°F).
The Kelvin scale is the primary unit of temperature measurement in science and starts at absolute zero.
Room temperature (20-25°C) feels different based on humidity and air movement.
The highest temperature ever recorded on Earth was 54°C (129°F) in Death Valley, California.
