To convert a delta temperature from degrees Fahrenheit to degrees Celsius, the formula is {ΔT} °F = 9 / 5 {ΔT} °C. To convert a delta temperature from degrees Celsius to kelvin, it is 1:1 ({ΔT} °C = {ΔT} K).

This should be distinguished from temperatures expressed as negative numbers on non-thermodynamic Celsius or Fahrenheit scales, which are nevertheless higher than absolute zero. A system with a truly negative temperature on the Kelvin scale is hotter than any system with a positive temperature. If a negative-temperature system and a positive ...
Thus, to convert from units of Fahrenheit to units of Celsius, one subtracts 32 °F (the offset from the point of reference), divides by 9 °F and multiplies by 5 °C (scales by the ratio of units), and adds 0 °C (the offset from the point of reference).
In April 1975, Fahrenheit temperatures were replaced by Celsius. In September 1975, rainfall was first measured in millimetres and snow in centimetres . Since April 1976, wind speed , visibility , and barometric pressure have been in metric units, with the pressure in kilopascals instead of the hectopascals ( millibars ) used in most of the ...
To convert densities to moles per liter, multiply by 22.678 cm 3 mol/(L·g). Data obtained from CRC Handbook of Chemistry and Physics , 44th ed. pages 2560–2561, except for critical temperature line (31.1 °C) and temperatures −30 °C and below, which are taken from Lange's Handbook of Chemistry , 10th ed. page 1463.
Jacarandas in bloom at Plaza Miserere, Buenos Aires. Springs in Buenos Aires are typically mild during the day with cool to cold nights. [29] The average high is 22.8 °C (73.0 °F) while the average low is 13.4 °C (56.1 °F). [29]
The 2021 Western North America heat wave was an extreme heat wave that affected much of Western North America from late June through mid-July 2021. [5] The heat wave affected Northern California, Idaho, Western Nevada, Oregon, and Washington in the United States, as well as British Columbia, and in its latter phase, Alberta, Manitoba, the Northwest Territories, Saskatchewan, and Yukon, all in ...
