Comparison: Fahrenheit vs Kelvin
When to Use Each Unit
Fahrenheit: Primary temperature scale in the United States, Bahamas, Belize, and Cayman Islands. Used for weather, cooking, and medical measurements in these regions.
Kelvin: Primary temperature scale in scientific research, physics, chemistry, and astronomy. Used when absolute temperature measurements are required.
Common Conversion Values
- 32°F = 0°C (water freezing)
- 212°F = 100°C (water boiling)
- 98.6°F = 37°C (human body temperature)
- 68°F = 20°C (room temperature)
About (symbol:
Definition: Fahrenheit (symbol: °F) is a temperature scale where water freezes at 32°F and boils at 212°F at standard atmospheric pressure.
History: Created by German physicist Daniel Gabriel Fahrenheit in 1724. Originally based on the freezing point of brine and human body temperature.
Current Use: Primary temperature scale in the United States, Bahamas, Belize, and Cayman Islands. Used for weather, cooking, and medical measurements in these regions.
Examples: Weather: 14°F to 104°F, cooking: 350°F oven, fever: 102°F, refrigerator: 39°F
About (symbol:
Definition: Kelvin (symbol: K) is the SI base unit of temperature, with 0 K representing absolute zero (-273.15°C). No degree symbol is used.
History: Proposed by William Thomson (Lord Kelvin) in 1848 based on absolute zero. Became an SI base unit in 1954, redefined in 2019 using the Boltzmann constant.
Current Use: Primary temperature scale in scientific research, physics, chemistry, and astronomy. Used when absolute temperature measurements are required.
Examples: Liquid nitrogen: 77 K, room temperature: 293 K, surface of Sun: 5778 K
