Degrees Celsius to degrees Fahrenheit (°C to °F)
The answer, the exact formula and a table with the values people look up most.
1 °C = 33.8 °F°F = °C × 9/5 + 32Example: 30 °C = 86 °F
1 °C = 33.8 °F
Temperature does not convert by multiplying: each scale starts at a different point. That is why 0 °C is 32 °F and not zero.

The two units
Degree Celsius °C
The Celsius scale puts water freezing at 0 °C and boiling at 100 °C at sea level; almost every country uses it.
Degree Fahrenheit °F
On the Fahrenheit scale water freezes at 32 °F and boils at 212 °F; it is used mainly in the United States.
Frequently asked questions
How many degrees Fahrenheit are 30 degrees Celsius?
30 °C = 86 °F.
What is the formula to convert degrees Celsius to degrees Fahrenheit?
°F = °C × 9/5 + 32. 30 °C = 86 °F.
Is this conversion exact?
Yes. Temperature scales are not proportional — besides the ratio 9/5 there is a 32-degree offset — so you cannot convert with a single factor; the formula above is exact.
