Convert temperatures from Celsius to Fahrenheit.
Converted value = Source value × Conversion factor
For affine conversions such as temperature, an offset is also applied.The tool applies the relevant factor or temperature offset to the source value. Currency outputs require a current exchange-rate source, while cooking volume-to-weight conversions can vary by ingredient density and measuring method.
The fast and easy way to convert Celsius (C) to Fahrenheit (F). To convert temperatures in Celsius to Fahrenheit, multiply the Celsius by 9/5 and add 32. This online calculator should be helpful for weather temperatures, cooking, and science applications, as well as for temperature conversions during travel or in daily life.
To convert a temperature from Celsius to Fahrenheit, multiply the Celsius value by 9/5 and add 32.
1 degree Celsius = 1.8 degrees Fahrenheit on a temperature interval, but the change of absolute temperature needs to adding 32.
For example, 20°C is equal to 68°F.
The exact formula for converting Celsius to Fahrenheit is:
°F = (°C × 9/5) + 32
Since 9/5 equals 1.8, the formula can also be written as:
°F = (°C × 1.8) + 32
For the reverse conversion, use °C = (°F − 32) × 5/9.

| -20 | -4 |
| -10 | 14 |
| -5 | 23 |
| 0 | 32 |
| 5 | 41 |

| 18 | 64.4 |
| 20 | 68 |
| 21 | 69.8 |
| 22 | 71.6 |
| 23 | 73.4 |
| 24 | 75.2 |
| 25 | 77 |
| 30 | 86 |
| 32 | 89.6 |
| 35 | 95 |

Celsius, abbreviated as C, is one of the most common temperature scales used worldwide. The Celsius temperature scale is part of the metric system and is used in weather, cooking, science, and any other measurement of temperature. The freezing point of water on the Celsius scale is 0 C, and the boiling point is 100 C.
Fahrenheit ( F ), a scale used for commonly expressed temperatures in the U.S.. Waters freezes at 32 degrees F and boiles at 212 degrees F at normal air pressure.
The formula is °F = (°C × 9/5) + 32. Multiply the Celsius temperature by 9/5 and then add 32.
20°C is 68°F.
25°C is 77°F.
30°C is 86°F.
37°C is 98.6°F.
No Celsius and Fahrenheit are not the same temp scales. Celsius and Fahrenheit scale not just different scale zero point, also has different level degree value. To be converted to F on C, not just be multipied by some fixed number like 1.8 is the correct answer, needs to plus 32.
Enter a known source value, confirm the direction of conversion and compare the result with the level of precision required. Keep extra decimal places for technical work and round only at the final step.
Because Celsius and Fahrenheit are two completely different temperature scales the calculation involves both a multiplicative transformation, and an addition of an offset. The formula for converting Celsius to Fahrenheit is exact for positive, zero, and negative temperature values.
A fast mental calculation you can do is just multiply the Celsius value by 1.8 then add 32 (e.g., 15 °C x 1.8 + 32 = 59F); however this rounding leads to inaccurate results. The proper way is to use exactly 9/5.
| Temperature | Meaning |
|---|---|
| 0°C / 32°F | Water freezes under standard atmospheric pressure |
| 20°C / 68°F | Common indoor temperature reference |
| 25°C / 77°F | Warm room or outdoor temperature reference |
| 37°C / 98.6°F | Common reference for normal human body temperature |
| 100°C / 212°F | Water boils under standard atmospheric pressure |
The temperature on a weather forecast could be in Celsius (°C) or Fahrenheit (°F) depending on where it was recorded. So, the general comparison as a point of reference is: 10°C is equivalent to 50°F. 20°C is equivalent to 68°F. 30°C is equivalent to 86°F.
Most cooking temperature conversions: 180 °C - 356°F 200 °C - 392°F 220 °C - 428°F. Converting temperatures When recipes suggest both Celsius and Fahrenheit figures use the accurate converted version and do not just presume the difference stays consistent.
The same formula works for temperatures below zero. For example, -10°C converts to 14°F, while -20°C converts to -4°F. The two temperature scales are equal at -40 degrees, meaning -40°C = -40°F.
In addition to their differing reference points, Celsius and Fahrenheit have different sized intervals or degrees. Freezing occurs at 0 degrees Celsius or 32 degrees Fahrenheit. As a result, because one degree Celsius is larger than one Fahrenheit degree, you have to multiply by 9/5 and add 32.
