    The following is a timeline of low-temperature technology and cryogenic technology (refrigeration down to close to absolute zero, i.e. –273.15 °C, −459.67 °F or 0 K). [1] It also lists important milestones in thermometry , thermodynamics , statistical physics and calorimetry , that were crucial in development of low temperature systems.

    Portland cement clinker was first made (in 1825) in a modified form of the traditional static lime kiln. [2] [3] [4] The basic, egg-cup shaped lime kiln was provided with a conical or beehive shaped extension to increase draught and thus obtain the higher temperature needed to make cement clinker.

  8. Heating degree day - Wikipedia

    en.wikipedia.org/wiki/Heating_degree_day

    Since a 1 °C temperature change and a 1 K change in absolute temperature are the same, these cancel and no conversion is required. Example: For a typical New York City winter day with high of 40 °F and low of 30 °F, the average temperature is likely to be around 35 °F. For such a day we can approximate the HDD as (65 − 35) = 30.
