Conversion Formula
To convert Celsius to Fahrenheit, use the formula: F = (C × 9/5) + 32. This formula works because Celsius and Fahrenheit scale differ in size of degrees and starting points. Multiplying Celsius by 9/5 adjusts the scale difference, then adding 32 shifts the zero point from freezing in Celsius to freezing in Fahrenheit.
For example, converting 30°C: First multiply 30 by 9/5, which is 30 × 1.8 = 54. Then add 32: 54 + 32 = 86°F.
Conversion Example
- 20°C to Fahrenheit:
- Multiply 20 by 9/5: 20 × 1.8 = 36
- Add 32: 36 + 32 = 68°F
- So, 20°C equals 68°F
- 0°C to Fahrenheit:
- Multiply 0 by 9/5: 0 × 1.8 = 0
- Add 32: 0 + 32 = 32°F
- Freezing point in Fahrenheit is 32°F
- 15°C to Fahrenheit:
- Multiply 15 by 9/5: 15 × 1.8 = 27
- Add 32: 27 + 32 = 59°F
- Therefore, 15°C equals 59°F
- 40°C to Fahrenheit:
- Multiply 40 by 9/5: 40 × 1.8 = 72
- Add 32: 72 + 32 = 104°F
- 40°C is 104°F in Fahrenheit

Conversion Definitions
Celsius: Celsius is a temperature scale based on the freezing point of water at 0 degrees and boiling point at 100 degrees under standard atmospheric conditions. It divides the temperature range between freezing and boiling water into 100 equal parts called degrees Celsius.
Fahrenheit: Fahrenheit is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under normal atmospheric pressure. The scale divides the range between freezing and boiling into 180 equal increments called degrees Fahrenheit.
Conversion FAQs
Why do we add 32 when converting Celsius to Fahrenheit?
Adding 32 shifts the temperature scale to align freezing point of water in Fahrenheit to 32 degrees. Celsius starts at 0 for freezing, but Fahrenheit’s zero point is much colder, so 32 moves the adjusted value to correct Fahrenheit scale position.
Can I convert Fahrenheit to Celsius using the same formula?
No, converting Fahrenheit to Celsius requires a different formula: subtract 32 from the Fahrenheit value then multiply by 5/9. These steps reverse the scale adjustment and offset applied in Celsius to Fahrenheit conversion.
Is the conversion formula accurate for all temperatures?
The formula works accurately for measuring temperatures in everyday weather and science. However, at very extreme temperatures like near absolute zero, slight deviations can appear due to physical properties of materials, but for common use, it remains precise.
Does the Celsius scale have the same degree size as Fahrenheit?
No, one degree Celsius covers a larger temperature interval than one degree Fahrenheit. Specifically, 1°C equals 1.8°F, which is why the formula multiplies by 9/5 to scale the size of degrees properly between the two.
Why is 30 degrees Celsius considered warm in Fahrenheit?
Because 30°C converts to 86°F, which is quite warm for most climates. Fahrenheit scale numbers are higher, so 86°F represents a temperature where people often feel hot, suitable for summer weather and outdoor activities.
