A Fahrenheit to Kelvin Converter is an essential tool for converting temperature measurements between the Fahrenheit (°F) scale (commonly used in the United States) and the Kelvin (K) scale (the base unit of temperature in the International System of Units). This conversion is crucial for:

• Scientific research and experiments
• Engineering applications
• Advanced physics and chemistry calculations
• Meteorological studies

Key Temperature Reference Points

• Absolute zero: -459.67°F = 0K
• Freezing point of water: 32°F = 273.15K
• Boiling point of water: 212°F = 373.15K
• Human body temperature: 98.6°F ≈ 310.15K

Conversion Formulas

Fahrenheit to Kelvin Formula

$$K=\frac{(\mathrm{°}F-32)}{1.8}+273.15$$

or

$$K=(\mathrm{°}F+459.67)\times \frac{5}{9}$$

Kelvin to Fahrenheit Formula

$$\mathrm{°}F=(K\times 1.8)-459.67$$

or

$$\mathrm{°}F=(K-273.15)\times 1.8+32$$

Manual Calculation Example

Problem: Convert 50°F to Kelvin
Solution:

$$K=\frac{(50-32)}{1.8}+273.15=\frac{18}{1.8}+273.15=10+273.15=283.15K$$

So, 50°F = 283.15K

Quick Conversion Tips

• Remember key reference points (especially 0K = -459.67°F)

• For rough estimates:

         a. Subtract 32 from °F, divide by 2, then add 273
         b. Example: 100°F → (100-32)/2 + 273 ≈ 34 + 273 = 307K (actual: 310.93K)

• Kelvin has no degree symbol (it's just K, not °K)
