Temperature Converter
Convert a temperature between Celsius, Fahrenheit, and Kelvin. Choose the From and To scales and the result is shown rounded to 2 decimals; for example, 25 C converts to 77 F.
What this calculator does
The Temperature Converter estimates your result instantly from the values you enter, using standard math & conversions formulas. Convert a temperature between Celsius, Fahrenheit, and Kelvin. Choose the From and To scales and the result is shown rounded to 2 decimals; for example, 25 C converts to 77 F. Calculations run in your browser, so nothing you type is sent to a server, and the output is an estimate rather than a certified or official figure.

About Temperature Converter
The Temperature Converter changes a temperature between Celsius, Fahrenheit, and Kelvin. It first converts your input to Celsius, then to the target scale, and rounds the answer to two decimal places.
Formula & Mathematical Calculation
Converted Temperature = f(Temperature, From, To)
Calculated according to standard math formulas implemented in the calculator core.
Calculation Example
Enter 25, set From to Celsius and To to Fahrenheit, then Calculate. The Converted Temperature box shows 77 F, and the note reads '25 C equals 77 F.'
Key Benefits
- Converts across all three common scales: Celsius, Fahrenheit, and Kelvin
- Rounds the converted temperature to two decimal places
- Restates the conversion in a plain sentence beneath the result
How to Use this Calculator
-
Enter the temperature
Type the value in the Temperature field. -
Pick the scales
Choose the From scale and the To scale from the two dropdowns. -
Read the result
Click Calculate and read the Converted Temperature box, shown with the target scale code.
Assumptions & Limitations
What the calculation assumes
- Every value you enter is treated as an exact, known amount.
- Any rate or interval you enter is assumed to hold for the whole period unless the form asks for it separately.
- Results use standard published formulas and account only for the values entered above.
- Rounding is applied for display; the underlying calculation uses your full precision.
- Results are returned in the same units you enter, unless the tool states the output unit.
What it does not cover
- Temperature Converter produces a calculated result for reference and learning, not a certified or official measurement.
- Real-world outcomes differ when tolerances, rounding rules or local standards apply.
- Definitions and standards vary by region and change over time; verify the convention that applies to your case.
- Figures are only as accurate as the inputs you supply — check them before acting on the result.
- For work where the result carries real consequences, confirm it against an authoritative source.
