1 Fahrenheit is approximately -17.2222 Celsius.
Table of Contents
The Fahrenheit temperature scale and Celsius scale measure temperature differently. To convert 1°F to Celsius, you subtract 32 and then multiply by 5/9, which results in about -17.2222°C.

Conversion Formula
The conversion from Fahrenheit to Celsius use the formula: C = (F – 32) × 5/9. This is because the Fahrenheit and Celsius scales have different zero points and increments per degree. Fahrenheit’s freezing point of water is 32°F, while Celsius is 0°C.
Subtracting 32 adjusts for the different zero points, and multiplying by 5/9 converts the scale increment. For example, to convert 1°F:
- Subtract 32: 1 – 32 = -31
- Multiply by 5/9: -31 × 5/9 = -17.2222
- So, 1°F equals approximately -17.2222°C.
Conversion Example
- Convert 50°F to Celsius:
- Subtract 32: 50 – 32 = 18
- Multiply by 5/9: 18 × 5/9 = 10
- Result: 50°F = 10°C
- Convert 100°F to Celsius:
- Subtract 32: 100 – 32 = 68
- Multiply by 5/9: 68 × 5/9 ≈ 37.7778
- Result: 100°F ≈ 37.7778°C
- Convert -40°F to Celsius:
- Subtract 32: -40 – 32 = -72
- Multiply by 5/9: -72 × 5/9 = -40
- Result: -40°F = -40°C
- Convert 77°F to Celsius:
- Subtract 32: 77 – 32 = 45
- Multiply by 5/9: 45 × 5/9 = 25
- Result: 77°F = 25°C

Conversion Definitions
Fahrenheit: Fahrenheit is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric conditions. It was created by Daniel Gabriel Fahrenheit, and is mainly used in the United States for everyday temperature measurements.
Celsius: Celsius is a temperature scale based on the freezing point of water at 0 degrees and boiling point at 100 degrees at sea level. It is widely used around the world for scientific and daily temperature measurement, providing a metric system for temperature.
Conversion FAQs
Why does 1 degree Fahrenheit convert to a negative Celsius value?
Because the Fahrenheit scale starts its freezing point of water at 32°F, any temperature below that number converts to a negative Celsius value. Since 1°F is less than 32, subtracting 32 gives a negative number, which after multiplication by 5/9 remains negative.
Can I use the same formula to convert Celsius back to Fahrenheit?
No, the formula is different. To convert Celsius to Fahrenheit, you multiply the Celsius value by 9/5 and then add 32. Using the Fahrenheit to Celsius formula in reverse will not give correct results because the scales are offset differently.
Is the conversion formula accurate for all temperatures?
Yes, the formula C = (F – 32) × 5/9 applies to any temperature value on the Fahrenheit scale. It’s a linear conversion, so works for negative, positive, and zero values equally without any exceptions.
Why do we subtract 32 in the conversion formula?
Subtracting 32 adjusts for the difference in zero points between the two scales. Fahrenheit’s zero is set lower, so 32°F corresponds to 0°C. Removing 32 shifts the scale so the conversion to Celsius works correctly.
Can this conversion be done using other methods?
Besides the formula, you can use conversion tables, online tools, or programmable calculators. But the formula remains the basis for all accurate conversions between Fahrenheit and Celsius.
