Temperature Scale Facts
Celsius Scale:
Water freezes at 0°C and boils at 100°C (at sea level)
Kelvin Scale:
Absolute zero is 0 K, water freezes at 273.15 K, boils at 373.15 K
Absolute Zero:
-273.15°C or 0 K – the lowest possible temperature
Conversion:
K = °C + 273.15 (add 273.15 to Celsius to get Kelvin)
