23 degrees Celsius equals 73.4 degrees Fahrenheit.
To convert 23 Celsius to Fahrenheit, you multiply by 9/5 and then add 32. This changes the Celsius temperature scale, based on water’s freezing and boiling points, to the Fahrenheit scale which uses different reference points.

Conversion Formula
The formula to convert Celsius (°C) to Fahrenheit (°F) is: F = (C × 9/5) + 32. This means you multiply the Celsius temperature by 9 divided by 5, then add 32 to the product. The reason this works is because Celsius and Fahrenheit have different zero points and scaling intervals.
Since Celsius sets the freezing point of water at 0°C and boiling at 100°C, and Fahrenheit sets these at 32°F and 212°F respectively, the formula adjusts for both scale difference and offset.
For example, converting 23°C step-by-step:
- Multiply 23 by 9/5: 23 × 1.8 = 41.4
- Add 32: 41.4 + 32 = 73.4°F
Conversion Example
- Convert 10°C to Fahrenheit:
- 10 × 9/5 = 18
- 18 + 32 = 50°F
- Convert -5°C to Fahrenheit:
- -5 × 9/5 = -9
- -9 + 32 = 23°F
- Convert 37°C to Fahrenheit:
- 37 × 9/5 = 66.6
- 66.6 + 32 = 98.6°F
- Convert 0°C to Fahrenheit:
- 0 × 9/5 = 0
- 0 + 32 = 32°F
- Convert 15.5°C to Fahrenheit:
- 15.5 × 9/5 = 27.9
- 27.9 + 32 = 59.9°F

Conversion Definitions
Celsius: Celsius is a temperature scale where 0 degrees marks the freezing point of water and 100 degrees marks the boiling point at standard atmospheric pressure. It is widely used around the world for weather, cooking, and scientific measurements.
Fahrenheit: Fahrenheit is a temperature scale used mainly in the United States. Water freezes at 32 degrees and boils at 212 degrees on this scale. It divides the temperature range between freezing and boiling into 180 equal parts called degrees.
Conversion FAQs
Why does converting Celsius to Fahrenheit involve multiplying by 9/5?
The Celsius and Fahrenheit scales have different unit sizes. Celsius degrees are larger; each Celsius degree equals 1.8 Fahrenheit degrees. Multiplying by 9/5 (which is 1.8) adjusts the scale difference before adding the offset of 32 to match freezing points.
Can the conversion formula be reversed to convert Fahrenheit to Celsius?
Yes, to convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit value, then multiply by 5/9. This reverses the previous scale adjustment and offset, since Celsius zero is lower than Fahrenheit zero.
Why does the formula add 32 at the end?
Adding 32 accounts for the difference in zero points between the two scales. Water freezes at 0°C but at 32°F. Without adding 32, the converted values would be off by this fixed amount.
Is the conversion formula exact for negative temperatures too?
Yes, the formula works for negative temperatures as well. The linear relationship between the scales holds across all values, so multiplying by 9/5 and adding 32 applies for below freezing points just like above.
How precise is the conversion when using decimals?
Using decimals increases precision. The formula can output fractional Fahrenheit degrees, which is useful in fields needing accuracy, like science or engineering. Rounding depends on the context of usage.
