Minimum temperature map of the United States from 1871–1888 Maximum temperature map of the United States from 1871–1888. The following table lists the highest and lowest temperatures recorded in the 50 U.S. states, the District of Columbia, and the 5 inhabited U.S. territories during the past two centuries, in both Fahrenheit and Celsius.

For the United States, the extremes are 134 °F (56.7 °C) in Death Valley, California in 1913 and −79.8 °F (−62.1 °C) recorded in Prospect Creek, Alaska in 1971. The largest recorded temperature change in one place over a 24-hour period occurred on January 15, 1972 in Loma, Montana , when the temperature rose from −54 to 49 °F (−47. ...
* 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 average global temperature for the 12-month period to the end of May was 1.63 degrees Celsius (2.9 degrees Fahrenheit) above the pre-industrial average - making it the warmest such period ...
Highest dew point temperature: A dew point of 35 °C (95 °F) — while the temperature was 42 °C (108 °F) — was observed at Dhahran, Saudi Arabia, at 3:00 p.m. on 8 July 2003. [ 201 ] Highest heat index : In the observation above at Dhahran, Saudi Arabia, the heat index ("feels like" temperature) was 81.1 °C (178.0 °F).
A temperature interval of 1 °F was equal to an interval of 5 ⁄ 9 degrees Celsius. With the Fahrenheit and Celsius scales now both defined by the kelvin, this relationship was preserved, a temperature interval of 1 °F being equal to an interval of 5 ⁄ 9 K and of 5 ⁄ 9 °C. The Fahrenheit and Celsius scales intersect numerically at −40 ...
Most scientists measure temperature using the Celsius scale and thermodynamic temperature using the Kelvin scale, which is the Celsius scale offset so that its null point is 0 K = −273.15 °C, or absolute zero. Many engineering fields in the US, notably high-tech and US federal specifications (civil and military), also use the Kelvin and ...
