1 °C = 33.8 °F
Temperature scale conversion guide
Convert between Celsius, Fahrenheit, and Kelvin for weather forecasts, oven temperatures, laboratory notebooks, and engineering calculations. Temperature does not convert with a single ratio like length because each scale defines its zero point differently.
Celsius is based on the freezing and boiling points of water at sea level (0 °C and 100 °C). Fahrenheit is common in the United States for weather and cooking. Kelvin is the SI thermodynamic scale used in physics and chemistry; 0 K is absolute zero, and kelvin degrees are the same size as Celsius degrees.
When traveling or reading international recipes, you may need to convert oven settings between °C and °F. Scientists reporting room temperature might use 298 K instead of 25 °C. Unitivo applies the standard linear formulas between these scales on every calculation.
Always confirm critical values against official references in medical, food safety, or industrial processes. Learn more about how Unitivo works on our About page and in the FAQ.
Reference temperatures
- Water freezes: 0 °C = 32 °F
- Water boils (sea level): 100 °C = 212 °F
- Comfortable room: about 20 °C = 68 °F
- Body temperature: about 37 °C = 98.6 °F
- 0 K = −273.15 °C
Worked example
To convert 350 °F to Celsius: (350 − 32) × 5/9 ≈ 176.67 °C. To convert 25 °C to Fahrenheit: (25 × 9/5) + 32 = 77 °F.
