Convert Kelvin to Fahrenheit (K to °F) instantly with this live, customizable tool. Type or import values, and it shows accurate °F conversions right away. You control how it looks round the output, display formulas, and keep your original formatting if needed.
How to Use:
Type Kelvin values into the left-hand input box. Add one value per line or paste a list the tool converts them automatically as you type.
To load values from a file, click Choose File and select a .txt, .csv, .json, or other plain-text format. The tool reads the file and replaces the input area with its contents, triggering conversions immediately.
Use the toggles in the Options section to adjust the output:
- Round to 2 decimals simplifies the results (enabled by default)
- Show formula used explains each conversion step
- Keep empty lines maintains the original spacing from your input
After conversion, you can copy results, download them, or reset everything using the Clear All button.
What Kelvin to Fahrenheit | K to °F can do:
The tool converts each line using the formula:°F = (K − 273.15) × 9/5 + 32
It calculates each value independently. When rounding is turned on, results appear with two decimal places. Enabling the formula toggle shows full calculations like:(310.15K − 273.15) × 9/5 + 32 = 98.60°F
The output area flashes whenever it updates, and the line counter beneath it tells you how many items were processed. If you choose to keep empty lines, your original input structure stays intact.
Example:
Input:
273.15
373.15
0
310.15Output (formula ON):
(273.15K − 273.15) × 9/5 + 32 = 32.00°F
(373.15K − 273.15) × 9/5 + 32 = 212.00°F
(0K − 273.15) × 9/5 + 32 = -459.67°F
(310.15K − 273.15) × 9/5 + 32 = 98.60°FCommon Use Cases:
Use the Kelvin to Fahrenheit | K to °F converter for lab reports, engineering data, or science coursework. It helps students, researchers, and professionals get accurate results fast without reformatting data by hand.
