Celsius to Fahrenheit

Celsius to Fahrenheit uses F = C × 9/5 + 32. The inverse relationship for Celsius to Fahrenheit is C = (F − 32) × 5/9.

Celsius to Fahrenheit input definition: degrees Celsius use the scale where absolute zero is −273.15 °C. For Celsius to Fahrenheit, output definition: degrees Fahrenheit use a scale related to Celsius by F = C × 9/5 + 32.

Celsius to Fahrenheit check: 0 Celsius = 32 Fahrenheit. Celsius to Fahrenheit check: 20 Celsius = 68 Fahrenheit. Celsius to Fahrenheit check: 100 Celsius = 212 Fahrenheit.

Formula: Fahrenheit = Celsius x 9 / 5 + 32. Common checks help catch mistakes: freezing water is 0 Celsius or 32 Fahrenheit, room temperature is around 20 to 25 Celsius, and boiling water is around 100 Celsius at sea level. Use these reference points when the fahrenheit result will be used for weather, cooking, science homework, equipment settings, or travel planning.
