84°F is equal to approximately 302.039 kelvin.
To convert 84 degrees Fahrenheit to kelvin, you first convert Fahrenheit to Celsius, then add 273.15 to get kelvin. This two-step process accounts for the different starting points and scales of temperature measurement.

Conversion Formula
The formula to convert Fahrenheit (°F) to kelvin (K) involves two steps. First, convert Fahrenheit to Celsius using C = (F - 32) × 5/9. Second, convert Celsius to kelvin by adding 273.15 because kelvin starts at absolute zero, which is -273.15°C.
Thus, the full formula is: K = (F - 32) × 5/9 + 273.15.
For example, converting 84°F:
- Subtract 32 from 84: 84 – 32 = 52
- Multiply by 5/9: 52 × 5/9 ≈ 28.8889
- Add 273.15 to get kelvin: 28.8889 + 273.15 = 302.039
Conversion Example
- Convert 68°F to kelvin:
- 68 – 32 = 36
- 36 × 5/9 = 20
- 20 + 273.15 = 293.15 K
- Convert 100°F to kelvin:
- 100 – 32 = 68
- 68 × 5/9 ≈ 37.7778
- 37.7778 + 273.15 ≈ 310.9278 K
- Convert 32°F to kelvin:
- 32 – 32 = 0
- 0 × 5/9 = 0
- 0 + 273.15 = 273.15 K
- Convert 50°F to kelvin:
- 50 – 32 = 18
- 18 × 5/9 = 10
- 10 + 273.15 = 283.15 K

Conversion Definitions
F (Fahrenheit): Fahrenheit is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric pressure. It originated in the early 18th century and is mainly used in the United States for weather, cooking, and industrial processes. Values are measured in degrees Fahrenheit (°F).
Kelvin: Kelvin is the SI base unit for temperature measurement, starting at absolute zero, the coldest theoretically possible temperature. It uses the same increment as Celsius but starts at 0 K = -273.15°C. Kelvin is used in science and engineering where absolute temperature is needed, especially thermodynamics and physics.
Conversion FAQs
Why do we add 273.15 when converting Celsius to kelvin?
Kelvin is an absolute temperature scale based on absolute zero, the point where all thermal motion ceases. Since Celsius zero (0°C) is 273.15 degrees above absolute zero, you add 273.15 to convert a Celsius temperature into kelvin. This shifts the scale to start at absolute zero.
Can the conversion from Fahrenheit to kelvin result in negative values?
No, kelvin cannot be negative because it starts at absolute zero, the lowest possible temperature. Even very cold Fahrenheit temperatures convert to kelvin values above zero. If negative values appear, it usually means there was a mistake in the calculation or input.
Is the kelvin value exact when converting from Fahrenheit?
Kelvin values from Fahrenheit are exact when rounded properly, but since Fahrenheit and Celsius scales use fractional conversions, small rounding differences can appear. Using enough decimal places in calculations helps minimize these differences, but real-world measurements rarely require perfect exactness.
Why is the formula for Fahrenheit to kelvin different from Fahrenheit to Celsius?
Fahrenheit to Celsius just adjusts for different zero points and scale increments. Kelvin starts from absolute zero, so after converting Fahrenheit to Celsius you must add 273.15 to shift the scale to kelvin. The additional step accounts for the absolute zero baseline.
Is kelvin used outside scientific fields?
Kelvin is mostly used in science and engineering for precise temperature measurements. It’s uncommon in everyday life or weather forecasts, where Celsius or Fahrenheit dominate. However, kelvin’s absolute scale makes it necessary for physics, chemistry, and materials science work.
