The conversion of 0°F to Kelvin results in 255.3722 K. This means that at 0°F, the temperature is approximately 255.37 Kelvin.

To convert Fahrenheit to Kelvin, you start by subtracting 32 from the Fahrenheit value, then multiply that result by 5/9 to get Celsius, and finally add 273.15 to convert Celsius to Kelvin. For 0°F: (0 – 32) × 5/9 + 273.15 = 255.3722 K.

Conversion Result

0°F equals approximately 255.3722 Kelvin.

Conversion Formula

The formula to convert Fahrenheit to Kelvin is: K = (F – 32) × 5/9 + 273.15. It works because Fahrenheit is an offset scale from Celsius, which itself is a scaled version of Kelvin. First, you convert Fahrenheit to Celsius, then add 273.15 to get Kelvin. For example, for 0°F: (0 – 32) × 5/9 = -17.7778°C, then add 273.15, resulting in 255.3722 K.

Conversion Example

• Convert 20°F to Kelvin:
  • Subtract 32: 20 – 32 = -12
  • Multiply by 5/9: -12 × 5/9 = -6.6667°C
  • Add 273.15: -6.6667 + 273.15 = 266.4833 K
• Convert -10°F to Kelvin:
  • Subtract 32: -10 – 32 = -42
  • Multiply by 5/9: -42 × 5/9 = -23.3333°C
  • Add 273.15: -23.3333 + 273.15 = 249.8167 K
• Convert 100°F to Kelvin:
  • Subtract 32: 100 – 32 = 68
  • Multiply by 5/9: 68 × 5/9 = 37.7778°C
  • Add 273.15: 37.7778 + 273.15 = 310.9278 K
• Convert -40°F to Kelvin:
  • Subtract 32: -40 – 32 = -72
  • Multiply by 5/9: -72 × 5/9 = -40°C
  • Add 273.15: -40 + 273.15 = 233.15 K

Conversion Definitions

Fahrenheit (f): A temperature scale where 32°F is the freezing point of water, and 212°F is the boiling point at standard atmospheric pressure, used mainly in the United States. It is based on a scale devised by Daniel Gabriel Fahrenheit.

Kelvin (kelvin): The SI base unit for temperature, starting at absolute zero (0 K), where particles have minimal thermal motion. It is used in scientific contexts for precise temperature measurement, with increments equal to Celsius degrees.

Conversion FAQs

How do I convert a Fahrenheit temperature to Kelvin manually?

Subtract 32 from Fahrenheit, multiply the result by 5/9 to get Celsius, then add 273.15 to convert Celsius to Kelvin. For example, for 50°F: (50 – 32) × 5/9 = 9.4444°C, then add 273.15, resulting in 282.5944 K.

Is 0°F the same as absolute zero?

No, 0°F is not absolute zero. Absolute zero is 0 K or -459.67°F. 0°F is much warmer, roughly -17.78°C, and represents the freezing point of a specific brine solution, not the lowest possible temperature.

Why is Kelvin used in scientific experiments instead of Fahrenheit?

Kelvin is used because it starts at absolute zero, providing a true zero point for thermal motion, making calculations and comparisons more straightforward. Fahrenheit’s scale is arbitrary and not aligned with physical thermodynamic principles.

Can I convert Kelvin back to Fahrenheit easily?

Yes, by reversing the formula: F = (K – 273.15) × 9/5 + 32. This allows conversion from Kelvin to Fahrenheit for temperature readings in scientific data.

What is the significance of 255.37 Kelvin at 0°F?

This value marks the temperature in Kelvin corresponding to 0°F, showing how Fahrenheit’s scale relates to the absolute temperature scale of Kelvin. It indicates the temperature is well above absolute zero, despite being freezing in Fahrenheit.
