Fahrenheit to Kelvin online temperature conversion formula

Fahrenheit (°F)

Fahrenheit is a unit of temperature created in 1724 by German physicist Daniel Gabriel Fahrenheit.

• The freezing point of water = 32°F

• The boiling point of water = 212°F (at sea level and standard pressure)

The scale is divided into 180 equal parts between freezing and boiling.

Today, most countries use Celsius, but Fahrenheit is still common in the United States, Bahamas, Belize, and Cayman Islands, especially for weather forecasts, ovens, and thermostats.

Kelvin (K)

Kelvin is the SI base unit of thermodynamic temperature. It is widely used in physics, chemistry, astronomy, and engineering.

• Absolute zero = 0 K (−273.15°C or −459.67°F)

• Unlike Celsius and Fahrenheit, Kelvin does not use the term degrees it is simply written as K.

It was named after physicist William Thomson (Lord Kelvin) in 1848. The Kelvin scale is an absolute scale, making it ideal for scientific calculations.

Formula

• K = (°F + 459.67) × 5/9

• °F = (K × 9/5) − 459.67

Example: Convert 50°F to Kelvin: (50 + 459.67) × 5/9 = 283.15 K
