Convert Temperature °C °F K °R

Convert temperature between °C, °F, K, and °R instantly using this all-in-one temperature converter. You can choose any combination of input and output units, paste values or upload a file, and customize how results appear. It’s accurate, flexible, and easy to use.

How to Use:

Start by entering temperature values into the left-hand input box. Use one value per line or paste multiple rows at once the output updates as you type.

To convert from a file, click Choose File and upload a .txt, .csv, or similar plain-text file. The tool fills in the input area and converts your data automatically.

Above the input area, select the conversion mode using the radio buttons. You can choose any pair like °C → °F, K → °R, or °F → K.

Under Options, adjust how the output appears:

• Round to 2 decimals (default ON) trims all numbers cleanly
• Show formula used reveals the full calculation for each result
• Keep empty lines preserves spacing and blank rows from your input

Use Copy Output to grab results, Export Output to download them as a .txt file, or Clear All to reset the tool to demo defaults.

What Temperature °C °F K °R can do:

This tool supports the following conversions:

• °C ↔ °F
• °C ↔ K
• °C → °R
• °F → K or °R
• K → °C, °F, or °R
• °R → K

It applies the correct formula based on the mode you select. If you enable rounding, the results display with two decimal places. With formula mode on, you’ll see the math clearly, like:

(310.15K − 273.15) × 9/5 + 32 = 98.60

Every time you change input, the output flashes to confirm the update. A live counter underneath shows how many values were processed.

Example:

Input:

0
100
273.15
-40

Mode:

Kelvin → Fahrenheit

Output (with formula on):

(0K − 273.15) × 9/5 + 32 = -459.67
(100K − 273.15) × 9/5 + 32 = -279.67
(273.15K − 273.15) × 9/5 + 32 = 32.00
(310.15K − 273.15) × 9/5 + 32 = 98.60

Common Use Cases:

The Temperature °C °F K °R tool is perfect for scientists, students, engineers, or anyone converting between multiple temperature scales. It’s ideal for lab reports, climate data, cooking conversions, and thermodynamic work where accuracy and flexibility matter.

Temperature Conversion Table:

The Convert Temperature Table helps you quickly see how common Celsius temperatures translate into Fahrenheit, Kelvin, and Rankine. It starts with cold values like –30 °C and climbs to extreme heat like 50 °C covering the full range of temperatures people typically search online. Each row shows all four units side by side, making it easy to compare or convert at a glance. Whether you’re checking the weather, converting lab data, or just curious what 37 °C feels like in Fahrenheit, this table gives you accurate, readable results with no math required.

Useful Tools & Suggestions:

If you’re converting between multiple temperature units, Celsius to Fahrenheit °C to °F is a quick way to get common conversions done fast. And if you’re working in absolute scales, Kelvin to Rankine K to °R can be handy, especially for thermodynamic calculations or scientific work where those units come up more often.
