About Celsius to Fahrenheit Conversion
Converting Celsius to Fahrenheit is one of the most common temperature conversions. Celsius is used in most countries around the world, while Fahrenheit is mainly used in the United States. Our celsius to fahrenheit converter makes this conversion quick and easy.
The celsius scale was created by Anders Celsius in 1742. It sets the freezing point of water at 0 degrees and the boiling point at 100 degrees. The fahrenheit scale was created by Daniel Gabriel Fahrenheit in 1724. It sets the freezing point of water at 32 degrees and the boiling point at 212 degrees.
To convert celsius to fahrenheit, you multiply the celsius temperature by 9/5 and then add 32. This simple formula works for any temperature conversion from celsius to fahrenheit.
How to Convert Celsius to Fahrenheit
Step-by-Step Method
- Take your celsius temperature
- Multiply it by 9
- Divide the result by 5
- Add 32 to get fahrenheit
Formula: °F = (°C × 9/5) + 32
Quick Example
Convert 25°C to Fahrenheit:
25 × 9 = 225
225 ÷ 5 = 45
45 + 32 = 77°F
Common Celsius to Fahrenheit Conversions
Water Temperatures
- 0°C = 32°F (Freezing)
- 100°C = 212°F (Boiling)
- 37°C = 98.6°F (Body temp)
Weather Temperatures
- 20°C = 68°F (Room temp)
- 30°C = 86°F (Hot day)
- -10°C = 14°F (Cold day)
Cooking Temperatures
- 180°C = 356°F (Baking)
- 200°C = 392°F (Hot oven)
- 160°C = 320°F (Low heat)

Frequently Asked Questions
What is the formula to convert celsius to fahrenheit?
The formula is °F = (°C × 9/5) + 32. You multiply the celsius temperature by 9/5 and then add 32 to get the fahrenheit temperature.
Why do we add 32 when converting celsius to fahrenheit?
We add 32 because the freezing point of water is 0°C but 32°F. This 32-degree difference needs to be added to align the two temperature scales.
What temperature is the same in both celsius and fahrenheit?
-40 degrees is the same in both celsius and fahrenheit. At this temperature, -40°C equals -40°F.
Is celsius or fahrenheit more accurate?
Both scales are equally accurate. Celsius is more widely used worldwide and is part of the metric system, while fahrenheit is mainly used in the United States.
How do I convert negative celsius temperatures to fahrenheit?
Use the same formula: °F = (°C × 9/5) + 32. For example, -10°C = (-10 × 9/5) + 32 = -18 + 32 = 14°F.
