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.

Maximum temperature map of the United States from 1871-1888 Minimum temperature map of the United States from 1871-1888.. 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.
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).
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).
The hardiness scales do not take into account the reliability of snow cover in the colder zones. Snow acts as an insulator against extreme cold, protecting the root system of hibernating plants. If the snow cover is reliable, the actual temperature to which the roots are exposed will not be as low as the hardiness zone number would indicate.
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 ...
The last day of 24-hour temperature changes shows a huge 50-degree rise in temperatures over the Northern Plains, a huge 50-degree drop around Arkansas, and a significant rise of 35 degrees in ...
Temperatures often top 49 °C (120 °F) at Death Valley during the summer months. [2] The standard measuring conditions for temperature are in the air, 1.5 metres (4 ft 11 in) above the ground, and shielded from direct sunlight. [3] Global surface temperatures as a whole have been monitored since the 1880s when record keeping began. [4]
