Converting Temperatures: Kelvin to Fahrenheit
When working with absolute Kelvin temperatures in science, you may need to convert to the more commonly used Fahrenheit scale. This guide explains the straightforward process to convert temperatures from Kelvin to Fahrenheit.
Overview of Kelvin and Fahrenheit Scales
Kelvin and Fahrenheit are two important temperature measurements. Key details on each include:
Kelvin
- Absolute scale representing thermal energy
- 0 K equals -273.15°C
- Freezing point of water at 273.15 K
Fahrenheit
- Most common scale in the United States
- Water freezes at 32°F
- Water boils at 212°F
Converting between the two is often necessary in physics, chemistry, weather reports and other applications using precise temperatures.
Converting Kelvin to Fahrenheit Step-by-Step
Follow this method to convert any Kelvin temperature to Fahrenheit:
- Subtract 273.15 from the Kelvin temperature
- Multiply the result by 9/5
- Add 32
For example, converting 300 K to Fahrenheit:
- 300 K – 273.15 = 26.85
- 26.85 * (9/5) = 48.33
- 48.33 + 32 = 80.33°F
So 300 Kelvin equals 80.33 degrees Fahrenheit.
Handy Kelvin-Fahrenheit Conversion Table
Refer to this table for some common Kelvin values and their Fahrenheit equivalents:
| Kelvin | Fahrenheit |
|---|---|
| 0 K | -459.67°F |
| 273.15 K | 32°F |
| 300 K | 80.33°F |
| 350 K | 169.33°F |
Converting Fahrenheit to Kelvin
To convert Fahrenheit to Kelvin, reverse the previous steps:
- Subtract 32 from the Fahrenheit temperature
- Multiply result by 5/9
- Add 273.15
Key Takeaways for Kelvin to Fahrenheit Conversions
- Subtract 273.15 from any Kelvin temperature
- Then multiply this number by 9/5
- Finally, add 32 to get Fahrenheit
- Use a handy reference table for common conversions
- Reverse steps to convert Fahrenheit to Kelvin
With this easy-to-follow process, converting between the Kelvin absolute and Fahrenheit temperature scales becomes fast and straightforward.
Type a value in the Kelvin field to convert the value to Fahrenheit:
Fahrenheit:
kelvin to fahrenheit Formula
℉=((K-273.15)*1.8)+32
Example
Convert 100 Kelvin to degrees Fahrenheit:
T(°F) = 100K × 9/5 – 459.67 = -279.66 °F
Convert 300 Kelvin to degrees Fahrenheit:
T(°F) = 300K × 9/5 – 459.67 = 80.33 °F
