Historically, on the Fahrenheit scale the freezing point of water was 32 °F, and the boiling point was 212 °F (at standard atmospheric pressure). This put the boiling and freezing points of water 180 degrees apart. [8] Therefore, a degree on the Fahrenheit scale was 1 ⁄ 180 of the interval between the freezing point and the boiling point ...
The melting point of water at 1 atmosphere of pressure is very close to 0 °C (32 °F; 273 K), and in the presence of nucleating substances the freezing point of water is close to the melting point, but in the absence of nucleators water can supercool to −40 °C (−40 °F; 233 K) before freezing.
Freezing [1] or frost occurs when the air temperature falls below the freezing point of water (0 °C, 32 °F, 273 K). This is usually measured at the height of 1.2 metres above the ground surface. This is usually measured at the height of 1.2 metres above the ground surface.

If you’re away from home, set the thermostat no lower than 55 degrees. When the temperature drops below 20 degrees Fahrenheit, run a drip from the faucets. Even just a trickle of cold water can ...
The water in the Potomac River is just a few degrees above freezing - ranging from 33 to 36 degrees Fahrenheit. "At these frigid water temperatures (33 to 36 degrees Fahrenheit in the vicinity of ...
The degree Celsius (°C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval (a difference between two temperatures). From 1744 until 1954, 0 °C was defined as the freezing point of water and 100 °C was defined as the boiling point of water, both at a pressure of one standard atmosphere.
