100 degrees Fahrenheit equals 310.9278 Kelvin.
The conversion from Fahrenheit (°F) to Kelvin (K) involves adjusting for the offset in the Fahrenheit scale and scaling to the absolute temperature scale used in Kelvin. Specifically, Fahrenheit first converts to Celsius, then Celsius is converted to Kelvin by adding 273.15.

Conversion Formula
The formula to convert Fahrenheit (f) to Kelvin (k) is:
K = (F – 32) × 5/9 + 273.15
This works by first removing the Fahrenheit offset of 32 degrees, then converting the Fahrenheit degree size to Celsius by multiplying by 5/9. The Celsius temperature is then shifted to the Kelvin scale by adding 273.15, since Kelvin starts at absolute zero.
Step-by-step example for 100°F:
- Subtract 32 from 100: 100 – 32 = 68
- Multiply by 5/9: 68 × 5/9 ≈ 37.7778
- Add 273.15 to convert to Kelvin: 37.7778 + 273.15 ≈ 310.9278 K
Conversion Example
Convert 85°F to Kelvin:
- Subtract 32 from 85: 85 – 32 = 53
- Multiply 53 by 5/9: 53 × 5/9 ≈ 29.4444
- Add 273.15: 29.4444 + 273.15 = 302.5944 K
Convert 0°F to Kelvin:
- 0 – 32 = -32
- -32 × 5/9 ≈ -17.7778
- -17.7778 + 273.15 = 255.3722 K
Convert 212°F to Kelvin:
- 212 – 32 = 180
- 180 × 5/9 = 100
- 100 + 273.15 = 373.15 K

Conversion Definitions
f: Fahrenheit (°F) is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under sea level pressure. It is mainly used in the United States and some Caribbean countries for everyday temperature measurement like weather and cooking.
k: Kelvin (K) is an absolute temperature scale based on thermodynamic principles where zero Kelvin is absolute zero, the coldest possible temperature. Kelvin is widely used in science and engineering, especially in physics and chemistry, where precise temperature measurement needed.
Conversion FAQs
Can Fahrenheit values below zero be converted to Kelvin?
Yes, Fahrenheit temperatures below zero can be converted to Kelvin, but the result will be positive as Kelvin scale starts at absolute zero (0 K). When converting, negative Fahrenheit values will still produce valid Kelvin values as long as the temperature is above absolute zero (-459.67°F).
Why does the conversion formula subtract 32 before multiplying?
The subtraction of 32 adjusts for the offset in the Fahrenheit scale where zero is not the freezing point of water. This aligns the temperature to Celsius scale where zero is freezing, allowing the scale to be proportionally converted before adding 273.15 to get Kelvin.
Is the Kelvin temperature always higher than Fahrenheit?
No, Kelvin temperatures are not always higher in numeric value than Fahrenheit. Because Kelvin starts at absolute zero, its values are usually larger for everyday temperatures, but for very cold temperatures in Fahrenheit, Kelvin values can be closer or lower numerically depending on the range.
Can I use this formula for converting temperatures for cooking?
Yes, the formula works for any temperature conversion between Fahrenheit and Kelvin, including cooking temperatures. However, Kelvin is rarely used in cooking, so Fahrenheit or Celsius are more practical for kitchen measurements.
Does this conversion consider atmospheric pressure changes?
No, the formula assumes standard atmospheric pressure and does not adjust for pressure changes. Temperature conversion between Fahrenheit and Kelvin is purely mathematical and independent of environmental conditions like pressure.
