How it works

Temperature conversion uses both scaling and offset adjustments.

Formulas:
C → F: (°C × 9/5) + 32
F → C: (°F − 32) × 5/9
C → K: °C + 273.15
K → C: K − 273.15

How to interpret results:
- Celsius: used in most countries and weather reports
- Fahrenheit: used mainly in the United States
- Kelvin: used in science and engineering

Use this tool when comparing temperatures across regions or converting scientific values.

Examples

  • Weather: Convert °F to °C when traveling internationally.
  • Cooking: Convert oven temperatures between systems.
  • Science: Convert °C to Kelvin for experiments.

Examples:

  • 0°C = 32°F = 273.15 K
  • 100°C = 212°F = 373.15 K
  • 98.6°F ≈ 37°C (body temperature)
  • 300 K ≈ 26.85°C

FAQ

  • Why is temperature conversion different?

    Unlike other units, temperature includes both scaling and offsets (e.g., +32 or +273.15).

  • Can I use negative values?

    Yes. Temperatures like −10°C or −40°F are valid and handled correctly.

  • Why do results sometimes look rounded?

    Some conversions produce long decimals, so values are formatted for readability.

  • What is absolute zero?

    Absolute zero is 0 K (−273.15°C), the lowest possible temperature.

  • Why is −40 the same in C and F?

    At −40, both Celsius and Fahrenheit scales intersect.

  • Is my data stored?

    No. All calculations run locally in your browser.
