About Fahrenheit
The Fahrenheit scale is a temperature scale where the freezing point of water is 32°F and the boiling point is 212°F (at standard atmospheric pressure). It is primarily used in the United States.
Facts About Fahrenheit
- Water freezes at 32°F and boils at 212°F (at sea level)
- Named after German physicist Daniel Gabriel Fahrenheit (1686–1736)
- 180 degrees between freezing and boiling points
- Normal human body temperature is approximately 98.6°F
- Still used in the United States, Belize, and some Caribbean nations
Common Uses
- Weather forecasts in the United States
- Oven temperatures for cooking and baking
- Medical temperature monitoring in the US
- Industrial temperature controls in North America
- Historical scientific measurements
History
The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in 1724. He based the scale on three fixed points: 0°F (the freezing point of brine), 32°F (the freezing point of water), and 96°F (body temperature, which was later refined to 98.6°F). The scale became widely used in the English-speaking world before the metric system gained global adoption.
About Kelvin
The Kelvin is the base unit of thermodynamic temperature in the International System of Units (SI). It is defined as the fraction 1/273.16 of the thermodynamic temperature of the triple point of water.
Facts About Kelvin
- 0 K is absolute zero, the lowest possible temperature
- No negative temperatures exist on the Kelvin scale
- Water freezes at 273.15 K and boils at 373.15 K (at sea level)
- Named after Irish-Scottish physicist William Thomson, 1st Baron Kelvin (1824–1907)
- The only SI temperature unit that does not use the degree symbol (°)
Common Uses
- Scientific research and thermodynamics
- Color temperature in lighting and photography
- Astronomy and space science
- Low-temperature physics experiments
- Semiconductor manufacturing
History
The Kelvin scale was proposed by William Thomson (Lord Kelvin) in 1848. It was designed to provide an absolute thermodynamic temperature scale, independent of any specific substance's properties. The scale was redefined in 2019 based on the Boltzmann constant, ensuring it remains stable and precise for scientific applications.

Conversion Examples
Convert 1 Fahrenheit to Kelvin
- Conversion Formula: K = (°F - 32) ÷ 1.8 + 273.15
- Calculation: (1°F - 32) ÷ 1.8 + 273.15 = 255.928K
Convert 10 Fahrenheit to Kelvin
- Conversion Formula: K = (°F - 32) ÷ 1.8 + 273.15
- Calculation: (10°F - 32) ÷ 1.8 + 273.15 = 260.928K
Convert 100 Fahrenheit to Kelvin
- Conversion Formula: K = (°F - 32) ÷ 1.8 + 273.15
- Calculation: (100°F - 32) ÷ 1.8 + 273.15 = 310.928K
Convert 1,000 Fahrenheit to Kelvin
- Conversion Formula: K = (°F - 32) ÷ 1.8 + 273.15
- Calculation: (1,000°F - 32) ÷ 1.8 + 273.15 = 810.928K
