50 degrees Fahrenheit converts to 283.15 kelvin.
This means that if you have a temperature reading of 50°F, it is equivalent to 283.15 kelvin on the kelvin scale. The conversion involves first shifting Fahrenheit to Celsius, then shifting Celsius to kelvin. This ensures an accurate transformation between the two temperature units.

Conversion Formula
The formula for turning Fahrenheit to kelvin is:
K = ((F - 32) × 5/9) + 273.15
First, you subtract 32 from the Fahrenheit value. This aligns the zero point for Celsius, since water freezes at 32°F. Next, multiply by 5/9 to convert the result into Celsius. Finally, adding 273.15 shifts Celsius to kelvin, matching the absolute temperature scale.
Step-by-step for 50°F:
- Subtract 32 from 50: 50 – 32 = 18
- Multiply by 5/9: 18 × 5/9 = 10
- Add 273.15: 10 + 273.15 = 283.15
So, 50°F = 283.15 K.
Conversion Example
- Convert 32°F to kelvin:
- Subtract 32: 32 – 32 = 0
- Multiply by 5/9: 0 × 5/9 = 0
- Add 273.15: 0 + 273.15 = 273.15
- So, 32°F = 273.15 K
- Convert 68°F to kelvin:
- Subtract 32: 68 – 32 = 36
- Multiply by 5/9: 36 × 5/9 = 20
- Add 273.15: 20 + 273.15 = 293.15
- So, 68°F = 293.15 K
- Convert 0°F to kelvin:
- Subtract 32: 0 – 32 = -32
- Multiply by 5/9: -32 × 5/9 = -17.7778
- Add 273.15: -17.7778 + 273.15 = 255.3722
- So, 0°F ≈ 255.3722 K
- Convert 100°F to kelvin:
- Subtract 32: 100 – 32 = 68
- Multiply by 5/9: 68 × 5/9 = 37.7778
- Add 273.15: 37.7778 + 273.15 = 310.9278
- So, 100°F ≈ 310.9278 K

Conversion Definitions
f: The Fahrenheit scale is a temperature measurement system where water freezes at 32 degrees and boils at 212 degrees at 1 atm pressure. Used, especially, in the United States and some Caribbean nations. The scale was first proposed by Daniel Gabriel Fahrenheit in 1724.
kelvin: Kelvin is the SI base unit for thermodynamic temperature. It starts at absolute zero, which is the theoretical point where all molecular motion stops. Zero kelvin equals -273.15°C. Used in science, engineering, and physics for absolute temperature readings.
Conversion FAQs
Why is kelvin used instead of Celsius or Fahrenheit for scientific calculations?
Kelvin is used since it starts from absolute zero, the coldest possible temperature. That way, temperatures always stay positive and calculations about energy or molecular movement becomes easier to handle, especially in chemistry and physics experiments.
Can a Fahrenheit value be negative, and will the kelvin value still make sense?
Yes, Fahrenheit temperatures can be negative, but kelvin results will stay positive as long as the Fahrenheit value is above -459.67°F. Below that, it would be below absolute zero, which isn’t physically possible according to the laws of physics.
Do I need to use parentheses in the formula, or will the math work anyway?
It helps to use parentheses: ((F – 32) × 5/9) + 273.15. If you skip them, you’ll get the wrong order of operations, so the answer will end up being incorrect. Parentheses group the subtraction and multiplication so the calculation becomes accurate.
Is it possible to convert kelvin back to Fahrenheit, and how is it done?
You can reverse the conversion. To do this, subtract 273.15 from kelvin, multiply the result by 9/5, then add 32. The formula looks like: F = (K – 273.15) × 9/5 + 32. This will return the original Fahrenheit temperature.
