Conversion Formula
The formula to convert Celsius (c) to Fahrenheit (f) is: f = (c × 9/5) + 32. This formula works because Celsius and Fahrenheit have different zero points and scale sizes. Celsius sets freezing water at 0, while Fahrenheit sets it at 32. The ratio 9/5 accounts for how many Fahrenheit degrees equal one Celsius degree.
Step-by-step calculation for 0°C:
- Multiply 0 by 9/5: 0 × 9/5 = 0
- Add 32 to the result: 0 + 32 = 32
- Therefore, 0°C equals 32°F.
Conversion Example
Convert 20°C to Fahrenheit:
- Multiply 20 by 9/5: 20 × 9/5 = 36
- Add 32: 36 + 32 = 68
- So, 20°C is 68°F.
Convert -10°C to Fahrenheit:
- Multiply -10 by 9/5: -10 × 9/5 = -18
- Add 32: -18 + 32 = 14
- Therefore, -10°C equals 14°F.
Convert 37°C to Fahrenheit:
- Multiply 37 by 9/5: 37 × 9/5 = 66.6
- Add 32: 66.6 + 32 = 98.6
- Thus, 37°C corresponds to 98.6°F.

Conversion Definitions
Celsius (°C): Celsius is a temperature scale used worldwide for measuring temperature. It sets the freezing point of water at 0 degrees and boiling point at 100 degrees under standard atmospheric pressure. The scale is divided into 100 equal parts, called degrees Celsius.
Fahrenheit (°F): Fahrenheit is a temperature scale mainly used in the United States. It defines freezing water at 32 degrees and boiling water at 212 degrees, dividing the scale into 180 equal intervals. It differs from Celsius in zero point and unit size.
Conversion FAQs
Why does zero Celsius equal 32 Fahrenheit?
Zero Celsius equals 32 Fahrenheit because the two scales use different zero points and unit sizes. Celsius sets freezing water at 0, while Fahrenheit sets it at 32. The formula adjusts for both the zero offset and the scale difference using multiplication and addition.
Can the Celsius to Fahrenheit formula be reversed?
Yes, to convert Fahrenheit back to Celsius, you subtract 32 from the Fahrenheit value and then multiply by 5/9. This reverses the original formula, accounting for the different zero points and scale sizes between the two units.
Is the 9/5 factor exact or approximate?
The 9/5 factor is exact and comes from the ratio between Fahrenheit and Celsius degree sizes. One Celsius degree equals 1.8 Fahrenheit degrees, which is exactly 9 divided by 5. It is not an approximation but a fundamental difference in scale graduations.
What if I enter a non-numeric value in the conversion tool?
The tool ignores non-numeric inputs and clears the output field. It only calculates and displays results when a valid number is entered in the input field, preventing errors or invalid conversions.
Does the formula work for temperatures below zero Celsius?
Yes, the formula works for any temperature, including negative Celsius values. The multiplication and addition correctly adjust for negative inputs, producing the corresponding Fahrenheit temperature even below freezing point.
