Celsius to Fahrenheit Converter
Convert Celsius to Fahrenheit instantly. Type a °C value and get the exact °F result. Formula: °F = (°C × 9/5) + 32.
The Celsius-to-Fahrenheit conversion is one of the most searched unit conversions globally, driven by the daily need to interpret weather forecasts, cooking temperatures, and body temperatures between the US (Fahrenheit) and the rest of the world (Celsius). The formula is: °F = (°C × 9/5) + 32, or equivalently °F = (°C × 1.8) + 32. For weather, the most referenced benchmarks: 0°C is freezing (32°F), 20°C is a comfortable room temperature (68°F), 37°C is normal body temperature (98.6°F), and 100°C is boiling water (212°F). American weather forecasts report summer highs of 95–100°F (35–37.8°C) while European heatwave coverage uses the same temperatures in Celsius. In cooking, European recipes specify oven temperatures in Celsius; American recipes use Fahrenheit. A recipe calling for 180°C is asking for 356°F — the typical moderate oven temperature. 200°C = 392°F; 220°C = 428°F; 160°C = 320°F. For candy and chocolate work, precise temperature control matters: hard crack sugar stage is 149–154°C (300–310°F). For body temperature, 38°C is a fever in Celsius (100.4°F). US emergency rooms still document temperatures in Fahrenheit while international medical literature uses Celsius exclusively.

Frequently Asked Questions
What is the formula to convert Celsius to Fahrenheit?
°F = (°C × 9/5) + 32, which can also be written as °F = (°C × 1.8) + 32. For example, 25°C = (25 × 1.8) + 32 = 45 + 32 = 77°F.
What temperature is the same in both Celsius and Fahrenheit?
-40°C = -40°F. This is the only point where the two scales coincide. Setting the equations equal: (C × 9/5) + 32 = C solves to C = -40.
What is 100°C in Fahrenheit?
100°C = 212°F. This is the boiling point of water at sea level (standard atmospheric pressure of 101.325 kPa).
What is body temperature in Celsius?
Normal body temperature is 37°C (98.6°F). A fever is typically defined as above 38°C (100.4°F). Hypothermia begins below 35°C (95°F).
