Celsius to Fahrenheit Converter °C → °F
1 °C equals 33.8 °F — note this scale uses an offset formula, not simple multiplication. Type a value below — the conversion happens instantly, entirely on your device.
20 °C = 68 °F
20 degrees Celsius = 68 degrees Fahrenheit
20 × 1.8 + 32 = 68
These scales have different zero points, so the conversion multiplies by 1.8 and then shifts by +32.
How to convert degrees Celsius to degrees Fahrenheit
°F = (°C × 9/5) + 32 — multiply the Celsius temperature by 9/5 (i.e. 1.8), then add 32.
Example: 20 °C = 68 °F.
To convert the other way: °C = (°F − 32) × 5/9 — or use the dedicated °F to °C converter .
Celsius-to-Fahrenheit is the most common temperature conversion — weather, cooking and body temperature. Anchor points worth memorizing: 0 °C = 32 °F (freezing), 20 °C = 68 °F (room temperature), 37 °C = 98.6 °F (body temperature), 100 °C = 212 °F (boiling). Mental shortcut: double the Celsius and add 30 (20 °C → 70 °F, close to the exact 68 °F). Note that −40° is the same in both scales.

About the units
What is the Celsius scale?
Degrees Celsius (°C) set 0° at the freezing point of water and 100° at its boiling point (at standard pressure). It is the everyday temperature scale in almost every country.
What is the Fahrenheit scale?
Degrees Fahrenheit (°F) place water’s freezing point at 32° and boiling point at 212°. It is the everyday temperature scale in the United States.
Frequently asked questions
How many degrees Fahrenheit are in 1 °C?
1 °C equals 33.8 °F — note this scale uses an offset formula, not simple multiplication.
What is the formula to convert degrees Celsius to degrees Fahrenheit?
°F = (°C × 9/5) + 32 — multiply the Celsius temperature by 9/5 (i.e. 1.8), then add 32.
Is this °C-to-°F converter accurate and private?
Yes. It uses the exact internationally defined conversion factors and computes results locally in your browser — your input is never sent to a server, and the page keeps working offline.
What is a fever of 38 °C in Fahrenheit?
38 °C is 100.4 °F — the common medical threshold for a fever.
What is 180 °C in Fahrenheit for baking?
180 °C equals 356 °F. Recipes usually round this to 350 °F, the standard moderate oven temperature.
