Python utility / temperature

Celsius to Fahrenheit.

Enter a temperature in degrees Celsius. A Python program on the server checks the value, performs the conversion, and builds the result page you see.

Whole numbers and decimals are accepted. JavaScript is not used.

Converted temperature 68°F

20°C equals 68°F.

How it works

Multiply, divide, then add.

°F = (°C × 9 ÷ 5) + 32

  1. Start with Celsius.

    The number entered in the form becomes the Celsius value.

  2. Scale it by 9/5.

    Multiplying by 9 and dividing by 5 accounts for the different size of Fahrenheit and Celsius degrees.

  3. Add 32.

    The two scales have different zero points, so 32 is added to place the result on the Fahrenheit scale.

Python-only processing: submitting the form sends the Celsius value to this same URL. The server-side Python script reads and validates it, uses Python’s Decimal type to apply the formula, then generates a fresh HTML response. No JavaScript, framework, database, or external service is involved.
