For an exact conversion between degrees Fahrenheit and Celsius, and kelvins of a specific temperature point, the following formulas can be applied. Here, f is the value in degrees Fahrenheit, c the value in degrees Celsius, and k the value in kelvins: f °F to c °C: c = f − 32 / 1.8 c °C to f °F: f = c × 1.8 + 32
Before the adoption of four standard time zones for the continental United States, many towns and cities set their clocks to noon when the sun passed their local meridian, pre-corrected for the equation of time on the date of observation, to form local mean solar time. Noon occurred at different times but time differences between distant ...

United States customary units form a system of measurement units commonly used in the United States and most U.S. territories [1] since being standardized and adopted in 1832. [2] The United States customary system developed from English units that were in use in the British Empire before the U.S. became an independent country.
For example, in New York City, the average high temperature trends downward by 10 degrees Fahrenheit from the start of November to the end of the month-from 59 to 49 degrees. Over the northern ...
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. ...
