About These Units
Need to turn Fahrenheit into Kelvin? The relationship is fixed: every Fahrenheit is worth 255.928 Kelvin, so 10 Fahrenheit lands at 2,559.28 Kelvin. Type any number into the tool above and the answer updates as you go — the formula and quick table below show the full picture.
Fahrenheit and Kelvin measure the same physical quantity but belong to different scales, so moving a figure from Fahrenheit into Kelvin — or back again — is a routine step whenever specifications, prices, or measurements cross between the two systems.
About Fahrenheit
Fahrenheit (°F) is a temperature scale where water freezes at 32°F and boils at 212°F.
Created by German physicist Daniel Fahrenheit in 1724, based on brine freezing point and human body temperature.
About Kelvin
Kelvin (K) is the SI base unit of temperature, where 0 K is absolute zero — the coldest possible temperature.
Proposed by Scottish physicist Lord Kelvin in 1848; uses the same degree size as Celsius but starts at absolute zero (-273.15°C).
When Conversion Is Needed
Fahrenheit and Kelvin belong to different measurement systems, so conversion becomes necessary when comparing values across the two units, or when forwarding a document or specification written in one unit to someone who uses the other. The quick-reference table on this page shows how common values in Fahrenheit translate to Kelvin, so memorizing or bookmarking the most frequently-used values is often a worthwhile shortcut.
Real-World Examples
Here is how familiar values in Fahrenheit translate into Kelvin.
