Kelvin to Fahrenheit Formula

°F = (K − 273.15) × 1.8 + 32 Also written as the Kelvin to Fahrenheit equation: °F = (K − 273.15) × 9/5 + 32

The kelvin to fahrenheit formula works in three steps. First, shift the starting point by subtracting 273.15 from Kelvin. Next, scale the degree size by multiplying by 1.8 (9/5). Finally, add 32 to match the Fahrenheit reference point. This is the exact kelvin to fahrenheit conversion formula used in science and engineering.

Worked Examples (How to Calculate Kelvin to Fahrenheit)

0 Kelvin to Fahrenheit
(0 − 273.15) × 1.8 + 32 = −459.67 °F
Absolute zero
273.15 Kelvin to Fahrenheit
(273.15 − 273.15) × 1.8 + 32 = 32 °F
Water freezes
300 Kelvin to Fahrenheit
(300 − 273.15) × 1.8 + 32 = 80.33 °F
Common reference point

Reverse Formula (Fahrenheit to Kelvin)

K = (°F − 32) × 5/9 + 273.15 This is the reverse equation for converting from Fahrenheit to Kelvin.

How to Convert Kelvin to Fahrenheit (Step by Step)

If you’re wondering how to convert kelvin to fahrenheit (or how do you convert kelvin to fahrenheit), follow this exact method. It’s the same process used by any reliable convert kelvin to fahrenheit calculator.

1
Start with the Kelvin value.
Example: 300 K
2
Subtract 273.15.
300 − 273.15 = 26.85
3
Multiply by 1.8 (9/5).
26.85 × 1.8 = 48.33
4
Add 32 to get Fahrenheit.
48.33 + 32 = 80.33 °F
Tip: If you want to change kelvin to fahrenheit quickly, use the formula above or the calculator. The Kelvin scale starts at absolute zero, so this conversion is not a simple add/subtract like some other scales.

Kelvin to Fahrenheit Scale Explained

The Kelvin (K) scale is an absolute temperature scale used in physics, chemistry, and astronomy. On the Kelvin scale, 0 K is absolute zero, so Kelvin never goes negative.

The Fahrenheit (°F) scale is widely used for weather, cooking, and daily measurements in the United States. Understanding the Kelvin to Fahrenheit scale helps when you’re reading scientific data in Kelvin but need everyday Fahrenheit values.

Quick wording note: “degrees kelvin to fahrenheit” is common in searches, but Kelvin is written as K (not °K). Fahrenheit uses degrees (°F).
