Convert Celsius to Fahrenheit

How to convert degrees Celsius to degrees Fahrenheit

The conversion is exact: °F = °C × 1.8 + 32, with no rounding buried in the constants. Both scales are precisely defined, so every Celsius reading has one true Fahrenheit equivalent. Reversing it means subtracting 32 first and then dividing by 1.8 — the same relationship read backwards.

1. Multiply the Celsius temperature by 1.8.
2. Add 32.
3. Read the result as degrees Fahrenheit.

Worked example: a European cake recipe calling for a 180 °C oven translates as 180 × 1.8 + 32 = 356 °F on an American dial.

What is a degree Celsius?

The degree Celsius is the temperature unit of daily life almost everywhere: weather reports, oven dials, thermostats, and fevers are quoted in it across Europe, Asia, Africa, Oceania, and the Americas outside the US. The scale puts the freezing point of water at 0 °C and its boiling point at 100 °C at sea level, and the SI defines it exactly through the kelvin. Anyone who grew up with it can feel the difference between 20 °C and 30 °C instantly — precisely the intuition that goes missing in front of a Fahrenheit forecast.

What is a degree Fahrenheit?

The degree Fahrenheit, named for the instrument maker Daniel Gabriel Fahrenheit, survives as the everyday temperature unit of the United States. On this scale water freezes at 32 °F and boils at 212 °F, while body temperature sits near 98.6 °F. American forecasts, ovens, and thermostats still assume it, which keeps this conversion permanently relevant for visitors.

When you’ll need °C to °F

• Reading US weather before a trip. A pleasant 20 °C afternoon shows as 68 °F on an American forecast, while a 30 °C summer day appears as 86 °F — knowing the mapping makes packing decisions instant.
• Baking with a US oven. Recipes from metric countries assume Celsius dials: 180 °C is 356 °F, 200 °C is 392 °F, and a hot 220 °C bake calls for 428 °F.
• Explaining a fever to an American doctor. Normal body temperature of 37 °C reads 98.6 °F, and an alarming 40 °C reads 104 °F — a distinction worth having ready in an urgent conversation.
• Setting a hotel thermostat in the US. If you keep your home at 25 °C, dial in 77 °F; the room will feel identical even though the number looks wildly different.
