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°F ≈ 37°C (approx.)
- 300 K ≈ 26.85°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.
