Temperature Conversion Formulas
Converting between Fahrenheit, Celsius, and Kelvin is essential in science and engineering. The most important thing to remember is that there is no direct formula for F to K; you must **convert to Celsius as an intermediate step**.
Formula: Fahrenheit to Kelvin (°F → K)
This is a two-step process:
- Step 1: Convert Fahrenheit to Celsius
°C = (°F - 32) × 5/9 - Step 2: Convert Celsius to Kelvin
K = °C + 273.15
Combined Formula: K = ((°F - 32) × 5/9) + 273.15
Other Conversion Formulas
- Kelvin to Fahrenheit (K → °F):
°F = (K - 273.15) × 9/5 + 32 - Celsius to Fahrenheit (°C → °F):
°F = (°C × 9/5) + 32 - Fahrenheit to Celsius (°F → °C):
°C = (°F - 32) × 5/9 - Celsius to Kelvin (°C → K):
K = °C + 273.15 - Kelvin to Celsius (K → °C):
°C = K - 273.15

Frequently Asked Questions (FAQ)
What is the formula for Fahrenheit (°F) to Kelvin (K)?
The formula is: K = (°F - 32) × 5/9 + 273.15. You must first convert Fahrenheit to Celsius (by subtracting 32 and multiplying by 5/9), and then add 273.15 to the result.
What is 0 Fahrenheit in Kelvin?
0 °F is equal to 255.372 K.
1. °C = (0 - 32) * 5/9 = -17.78 °C
2. K = -17.78 + 273.15 = 255.37 K
What is Absolute Zero (0 K) in Fahrenheit?
0 K (Absolute Zero) is equal to -459.67 °F. This is the lowest possible temperature.
