Temperature converter
Convert between Celsius, Fahrenheit, and Kelvin with formulas used in science and everyday life. Check oven settings (180 °C ↔ 350 °F), interpret US weather forecasts, or convert lab measurements.
How to convert temperature
1. Enter a value in Celsius, Fahrenheit, or Kelvin.
2. Select the target scale or read all three if shown together.
3. Use common reference points (freezing, body temp, boiling) to sanity-check.
4. Copy the converted value for your recipe, report, or thermostat.
Temperature conversion examples
Oven baking
180 °C = 356 °F (often rounded to 350 °F in cookbooks). 200 °C ≈ 392 °F.
Weather
25 °C = 77 °F — warm summer day. 0 °C = 32 °F — freezing.
Kelvin in science
300 K = 26.85 °C ≈ room temperature. 0 K is absolute zero (−273.15 °C).
When to use the temperature converter
• When you follow recipes or appliance manuals from another country.
• When you travel and interpret weather in °F vs °C.
• When you convert lab or industrial sensor readings for reports.
Reference points to remember
Freezing water: 0 °C = 32 °F. Boiling water at sea level: 100 °C = 212 °F. Human body: ~37 °C = 98.6 °F. These anchors help spot typos like 350 °C instead of 350 °F in recipes.
Frequently asked questions
What is the Celsius to Fahrenheit formula?
°F = (°C × 9/5) + 32. Reverse: °C = (°F − 32) × 5/9.
What is Kelvin?
Kelvin starts at absolute zero. K = °C + 273.15. No degree symbol on Kelvin in SI.
Is 100 °F hot?
100 °F ≈ 37.8 °C — slightly above normal body temperature; uncomfortable for outdoor weather.
Do ovens use exact conversions?
Markets round: 350 °F is the practical match for ~177 °C, not always exact 180 °C.
Why does Fahrenheit have a different zero?
Historical scale based on brine and body references — not aligned with water freezing at 0.
