Celsius to Fahrenheit, weather forecasts to oven dials
Temperature is the one conversion where a simple ratio is wrong. Fahrenheit is offset — the scales meet at −40° — so the real formula is °F = °C × 9/5 + 32. This converter uses exactly that, which is why 0 °C reads 32 °F and 100 °C reads 212 °F, as the scales promise.
This page presets the converter to Celsius → Fahrenheit. Type 20 and you get 68 °F for a comfortable room; type 180 and you get 356 °F for a moderate oven; type 37 and you get 98.6 °F, normal body temperature.
The quick table below lists the values people actually need — weather bands, baking temperatures, body readings — computed locally in your browser with no upload and no limits.

FAQs about this conversion
At what temperature are Celsius and Fahrenheit equal?
At −40°: −40 °C = −40 °F. That crossover comes from the 32-degree offset plus the 9/5 ratio, and the converter reproduces it exactly.
What is 37 °C in Fahrenheit?
37 × 9/5 + 32 = 98.6 °F — the classic normal body temperature. A degree up (38 °C) is 100.4 °F.
What oven temperature is 180 °C?
180 °C = 356 °F, which most US recipes call a “moderate” oven. The converter handles any oven dial value the same way.
