Comparison of temperature scales. * Normal human body temperature is 36.8 °C ±0.7 °C, or 98.2 °F ±1.3 °F. The commonly given value 98.6 °F is simply the exact conversion of the nineteenth-century German standard of 37 °C. Since it does not list an acceptable range, it could therefore be said to have excess (invalid) precision.
The "degree Kelvin" (°K) is a former name and symbol for the SI unit of temperature on the thermodynamic (absolute) temperature scale. [1] Since 1967, it has been known simply as the kelvin, with symbol K (without a degree symbol). [2] [3] [4] Degree absolute (°A) is obsolete terminology, often referring specifically to the kelvin but ...
The Kelvin scale is an absolute temperature scale that starts from 0 K, the lowest possible temperature (absolute zero), then rises by exactly 1 K for each 1 °C. The Kelvin scale was designed to be easily converted from the Celsius scale (symbol °C). Any temperature in degrees Celsius can be converted to kelvin by adding 273.15.
This definition also precisely related the Celsius scale to the Kelvin scale, which defines the SI base unit of thermodynamic temperature with symbol K. Absolute zero, the lowest temperature possible, is defined as being exactly 0 K and −273.15 °C. Until 19 May 2019, the temperature of the triple point of water was defined as exactly 273.16 ...
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.
Threshold of skin numbness if skin reaches this temperature 283.2 K: 10 °C: 50 °F: Minimum temperature for most plant growth (see Growing degree-day) 286.9 K: 12.7 °C: 54.9 °F: Coldest body temperature of a human that survived accidental hypothermia (a 2-year-old boy in Racławice, Poland, on November 30, 2014) 287.6 K: 14.44 °C: 58 °F
For higher temperatures, expected values for T − T 90 are below 0.1 mK for temperatures 4.2 K – 8 K, up to 8 mK at temperatures close to 130 K, to 0.1 mK at the triple point of water (273.1600 K), but rising again to 10 mK at temperatures close to 430 K, and reaching 46 mK at temperatures close to 1150 K.
