  2. Atmospheric temperature - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_temperature

    Average yearly temperature is 22.4 °C, ranging from an average minimum of 12.2 °C to a maximum of 29.9 °C. The average temperature range is 11.4 °C. [6] Variability throughout the year is small (standard deviation of 2.31 °C for the maximum monthly average and 4.11 °C for the minimum). The graph also shows the typical phenomenon of ...

  3. International Standard Atmosphere - Wikipedia

    en.wikipedia.org/wiki/International_Standard...

    To accommodate the lowest points on Earth, the model starts at a base geopotential altitude of 610 meters (2,000 ft) below sea level, with standard temperature set at 19 °C. With a temperature lapse rate of −6.5 °C (-11.7 °F) per km (roughly −2 °C (-3.6 °F) per 1,000 ft), the table interpolates to the standard mean sea level values of ...

  4. Lapse rate - Wikipedia

    en.wikipedia.org/wiki/Lapse_rate

    From 11 km up to 20 km (65,620 ft or 12.4 mi), the constant temperature is −56.5 °C (−69.7 °F), which is the lowest assumed temperature in the ISA. The standard atmosphere contains no moisture. Unlike the idealized ISA, the temperature of the actual atmosphere does not always fall at a uniform rate with height.

  5. Standard temperature and pressure - Wikipedia

    en.wikipedia.org/wiki/Standard_temperature_and...

    Since 1982, STP has been defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 1 bar (100 kPa, 10 5 Pa). NIST uses a temperature of 20 °C (293.15 K, 68 °F) and an absolute pressure of 1 atm (14.696 psi, 101.325 kPa). [3] This standard is also called normal temperature and pressure (abbreviated as NTP).

  6. Orders of magnitude (length) - Wikipedia

    ~5 mm Length of an average flea is 1–10 mm (usually <5 mm) [27] 2.54 mm One-tenth inch; distance between pins in DIP (dual-inline-package) electronic components 5.70 mm Diameter of the projectile in 5.56×45mm NATO ammunition 10 −2: 1 centimeter 20 mm Approximate width of an adult human finger: 54 mm × 86 mm

  7. R-value (insulation) - Wikipedia

    en.wikipedia.org/wiki/R-value_(insulation)

    For example, in winter it might be 2 °C outside and 20 °C inside, making a temperature difference of 18 °C or 18 K. If the material has an R-value of 4, it will lose 0.25 W/(°C⋅m 2 ). With an area of 100 m 2 , the heat energy being lost is 0.25 W/(K⋅m 2 ) × 18 °C × 100 m 2 = 450 W.

  8. Climate of Antarctica - Wikipedia

    en.wikipedia.org/wiki/Climate_of_Antarctica

    The lowest air temperature record, the lowest reliably measured temperature on Antarctica was set on 21 July 1983, when a temperature of −89.2 °C (−128.6 °F) was observed at Vostok Station. [2] [5] For comparison, this is 10.7 °C (19.3 °F) colder than subliming dry ice (at sea level pressure). The elevation of the location is 3,488 ...

  9. Climate of Salt Lake City - Wikipedia

    en.wikipedia.org/wiki/Climate_of_Salt_Lake_City

    July is the warmest month, with an average temperature of 77 °F (25.0 °C). Salt Lake City's record high minimum temperature is 81 °F (27.2 °C), set on July 18, 2016, and its record high temperature is 107 °F (42 °C), first set on July 26, 1960 and again on July 13, 2002 (although the temperature in 2002 was slightly higher).
