Science / Chemistry / Fahrenheit: A temperature scale proposed by Daniel Gabriel Fahrenheit (1686-1736) which uses the melting point of ice (32°F) and the boiling point of water at one atmosphere (212°F) as calibration points.

Fahrenheit Scale

Entertainment / Photography / Fahrenheit Scale: Scale of temperature named after its german originator, g. D. Fahrenheit. On this scale, the freezing point of water is 32° f, and the boiling point of water is 212° f. MORE

Fahrenheit Temperature Scale

Science / Weather / Fahrenheit Temperature Scale: A temperature scale where water at sea level has a freezing point of +32°F and a boiling point of +212°F. More commonly used in areas that observe the English system of measurement. Created in 1714 MORE

Degree Day

Science / Weather / Degree Day: A measure of the departure of the mean daily temperature from a given standard. That is one degree day for each degree (Fahrenheit or Celsius) of departure above or below the standard during one day. MORE


Science / Chemistry / Thermometer: An instrument for measuring temperature. MORE

Cooling Degree Day

Science / Weather / Cooling Degree Day: A cooling degree day is given for each degree that the daily mean temperature departs above the baseline of 75 degrees Fahrenheit. It is used to estimate the energy requirements and is an indication o MORE

Absolute Zero

Science / Chemistry / Absolute Zero: (0 K) The temperature at which the volume of an ideal gas becomes zero; a theoretical coldest temperature that can be approached but never reached. Absolute zero is zero on the Kelvin scale, -273.15° MORE
