How it works

Temperature conversion uses both a scale and an offset (unlike length/weight converters that are ratio-only). This tool converts through Celsius as an intermediate step when needed.

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

Displayed values may be rounded for readability, especially for repeating decimals.

Examples

  • 0°C = 32°F = 273.15 K
  • 100°C = 212°F = 373.15 K
  • 98.6°F37°C (approx.)
  • 300 K26.85°C (approx.)

FAQ

  • Why is temperature conversion different? Temperature uses offsets (like +32 or +273.15), not only ratios.
  • Can I enter negative values? Yes. Example: −10°C converts correctly.
  • Why do I see “approx.”? Some results have long decimals, so the display is rounded.
  • Does this tool save my inputs? No. Everything runs locally in your browser.
