80F

80°F (eighty degrees Fahrenheit) denotes a temperature on the Fahrenheit scale. It is a common value in weather reporting in the United States and other places that use Fahrenheit, where daily highs are often given in degrees Fahrenheit rather than Celsius. On the Fahrenheit scale, water freezes at 32°F and boils at 212°F at standard atmospheric pressure.

Conversions: 80°F is approximately 26.7°C. The conversion formula is °C = (°F − 32) × 5/9; °K = °C + 273.15. Therefore 80°F equals about 299.8 K.

Perception and use: At 80°F, the air is considered warm. Humidity can raise the perceived temperature via the heat index, so a day with high humidity may feel hotter than the same air temperature with low humidity. In everyday usage, 80°F is commonly used as a benchmark for warm summer conditions in regions that report weather in Fahrenheit.

Context: While Fahrenheit remains common in the United States, Celsius is used in most of the world for official weather reporting. Historical weather records in the U.S. often include Fahrenheit values, and conversions to Celsius are routinely provided for international comparison.
