Temperature Converter: Instant & Accurate

Convert any temperature — Celsius (°C), Fahrenheit (°F), Kelvin (K) — with scientific precision. Ideal for cooking, weather, science, or travel. No rounding errors. No data stored.

Example: 25°C = 77°F | 100°F = 37.78°C | 0°C = 273.15 K.

Real-World Use Cases

Weather Reports

Convert 30°C → 86°F for US forecasts.

Cooking & Baking

180°C oven = 356°F. Never burn again.

Science & Lab Work

37°C body temp = 310.15 K in research.

Freezing & Boiling

Water freezes at 0°C = 32°F, boils at 100°C = 212°F.

Conversion Formulas

Celsius → Fahrenheit

°F = (°C × 9/5) + 32

Fahrenheit → Celsius

°C = (°F - 32) × 5/9

Celsius → Kelvin

K = °C + 273.15

Kelvin → Celsius

°C = K - 273.15

Pro Temperature Tips

Memorize These

  • 20°C = 68°F (comfortable room)
  • 37°C = 98.6°F (normal body)
  • 100°C = 212°F (boiling)

Common Mistakes

  • Don’t confuse °C and °F in recipes
  • Kelvin has no degree symbol (just K)
  • Never use negative Kelvin — impossible!

Why Trust This Converter?

Speed: JS-powered, works offline (PWA-ready).

Frequently Asked Questions

0°C = 32°F — this is the temperature at which water freezes at standard atmospheric pressure.

Normal body temperature is about 37°C = 98.6°F = 310.15 K, though healthy individual readings can range roughly 36.1-37.2°C (97-99°F).

Kelvin starts at absolute zero (0 K = -273.15°C), the theoretical point where all molecular motion stops. This makes it the preferred scale for physics and chemistry since it has no negative values and directly relates to thermal energy.

No — 0 K (absolute zero) is the lowest possible temperature in the universe. Celsius and Fahrenheit can go negative, but Kelvin cannot by definition.

Use °F = (°C × 9/5) + 32. A common baking temperature of 180°C converts to 356°F — most recipes round this to 350°F, a small difference that rarely affects results.

°C = (°F − 32) × 5/9. For example, 68°F (room temperature) converts to exactly 20°C.

Water freezes at 0°C/32°F, room temperature is about 20-25°C/68-77°F, body temperature is 37°C/98.6°F, and water boils at 100°C/212°F (at sea level).
