M04/M07 indicates the temperature is −4 °C (25 °F) and the dew point is −7 °C (19 °F). An M in front of the number indicates that the temperature/dew point is below zero Celsius. Q1020 indicates the current altimeter setting (in QNH) is 1,020 hPa (30.12 inHg).
Temperature is a physical quantity that quantitatively expresses the attribute of hotness or coldness. Temperature is measured with a thermometer. It reflects the average kinetic energy of the vibrating and colliding atoms making up a substance.
The color temperature scale describes only the color of light emitted by a light source, which may actually be at a different (and often much lower) temperature. Color temperature has applications in lighting, photography, videography, publishing, manufacturing, astrophysics and other fields.
The current official highest registered air temperature on Earth is 56.7 °C (134.1 °F), recorded on 10 July 1913 at Furnace Creek Ranch, in Death Valley in the United States. [1] For ninety years, a former record that was measured in Libya had been in place, until it was decertified in 2012 based on evidence that it was an erroneous reading.
Since 2007, the Celsius temperature scale has been defined in terms of the kelvin, the SI base unit of thermodynamic temperature (symbol: K). Absolute zero, the lowest temperature, is now defined as being exactly 0 K and −273.15 °C. Countries by usage
Temperature measurement (also known as thermometry) describes the process of measuring a current temperature for immediate or later evaluation. Datasets consisting of repeated standardized measurements can be used to assess temperature trends.
The "degree Kelvin" (°K) is a former name and symbol for the SI unit of temperature on the thermodynamic (absolute) temperature scale. Since 1967, it has been known simply as the kelvin , with symbol K (without a degree symbol).
Lowest Temperature: −60 °F (−51.1 °C) February 2, 1996: Tower: March: Highest Temperature: 88 °F (31.1 °C) March 23, 1910: Montevideo: Lowest Temperature: −50 °F (−45.6 °C) March 2, 1897: Pine City: April: Highest Temperature: 101 °F (38.3 °C) April 22, 1980: Hawley: Lowest Temperature: −22 °F (−30 °C) April 6, 1979 ...
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). This standard is also called normal temperature and pressure (abbreviated as NTP ). However, a common temperature and pressure in use by NIST for thermodynamic experiments is 298.15 K (25° C , 77° F ) and 1 bar (14.5038 psi , 100 ...
Template expects a temperature between 837 K and 1,000,000 K in first parameter. Color is automatically labeled with the temperature unless the parameter text is filled. hexval tag can be used to return only an hexadecimal color code.
