Temperature Converter: Convert Between Celsius, Fahrenheit, and Kelvin

Our Temperature Converter provides accurate conversions between Celsius (°C), Fahrenheit (°F), and Kelvin (K)—the three most commonly used temperature scales. Whether you're working on scientific calculations, studying physics, traveling internationally, or simply curious about temperature conversions, this tool delivers precise results instantly.

What This Calculator Does

The Temperature Converter converts temperatures between three scales:

• Celsius (°C): The metric temperature scale used worldwide, with water freezing at 0°C and boiling at 100°C.
• Fahrenheit (°F): The temperature scale commonly used in the United States, with water freezing at 32°F and boiling at 212°F.
• Kelvin (K): The absolute temperature scale used in scientific contexts, where 0 K represents absolute zero.

Simply enter a temperature value, select the unit you're converting from, and instantly see the equivalent values in all three scales.

How to Use It

1. Enter temperature: Type the temperature value you want to convert.
2. Select source unit: Choose whether your input is in Celsius (°C), Fahrenheit (°F), or Kelvin (K).
3. Click "Calculate" to see conversions to all three temperature scales.

The calculator updates results automatically, showing Celsius, Fahrenheit, and Kelvin equivalents with precise decimal accuracy.

Interpreting Your Results

• Celsius: The metric temperature scale (0°C = freezing point of water).
• Fahrenheit: The US temperature scale (32°F = freezing point of water).
• Kelvin: The absolute temperature scale (273.15 K = 0°C = freezing point of water).

All results are displayed with 2 decimal places for accuracy. Note that Kelvin values below 0 are not physically possible (absolute zero is 0 K).

Common Mistakes to Avoid

• Confusing Celsius and Fahrenheit: Remember that 0°C = 32°F, not 0°F.
• Forgetting absolute zero: Temperatures cannot go below 0 K (-273.15°C or -459.67°F).
• Mixing up conversion formulas: The formulas differ for converting between scales—use the calculator to avoid errors.
• Using wrong precision: For scientific work, maintain decimal precision; for weather, whole numbers are usually sufficient.
