"From 1744 until 1954, 0 °C on the Celsius scale was defined as the freezing point of water and 100 °C was defined as the boiling point of water under a pressure of one standard atmosphere; this close equivalency is taught in schools today. However, the unit “degree Celsius” and the Celsius scale are currently, by international agreement, defined by two different points: absolute zero, and the triple point of VSMOW (specially prepared water). This definition also precisely relates the Celsius scale to the Kelvin scale, which is the SI base unit of temperature (symbol: K). Absolute zero—the temperature at which no energy remains in a substance—is defined as being precisely 0 K and −273.15 °C. The triple point of water is defined as being precisely 273.16 K and 0.01 °C."

The temperatures of boiling respectively freezing water could be different under different conditions.

I don't know at what temperature it boils but I do know it freezes at around 30 degrees F.

when we are going to talk about Celsius temperature scale the water boils at 100 degrees and freezes at 0 degrees..
But when it comes to Fahrenheit temperature scale the water boils at 212 degrees and freezes at 32 degrees..

water boils at 212 degrees and water freezes at 32 degrees

Death Lord: not so much. Everything was in a single Wikipedia article, actually. Thank you for your feedback!
