Converting temperatures from Fahrenheit to Kelvin is essential in scientific and engineering contexts. The conversion formula is: K = (°F + 459.67) × 5/9. For example, to convert 68°F to Kelvin: K = (68 + 459.67) × 5/9 ≈ 293.15 K. This formula accounts for the differences in scale and zero points between the Fahrenheit and Kelvin systems. The Fahrenheit scale sets the freezing point of water at 32°F and the boiling point at 212°F, while the Kelvin scale starts at absolute zero (0 K), the point where molecular motion ceases, making it fundamental in scientific measurements.
