About this conversion
Kelvin to Fahrenheit converts scientific temperature readings to the scale used in the United States. The Kelvin scale starts at absolute zero (0 K = −459.67°F) and has no negative values. Converting to Fahrenheit requires two steps: subtract 273.15 to get Celsius, then multiply by 9/5 and add 32. Or use the single formula °F = K × 1.8 − 459.67. Key references: 0 K = −459.67°F, 273.15 K = 32°F (water freezes), 373.15 K = 212°F (water boils), 310.15 K = 98.6°F (body temperature). This conversion is used when astrophysical data (often in Kelvin) needs to be expressed in Fahrenheit for US audiences, or when colour temperature ratings for light bulbs (2,700–6,500 K) need a Fahrenheit equivalent for comparison.
