Conversion Formula
The formula to convert Fahrenheit (°F) to Celsius (°C) is: (°F − 32) × 5/9 = °C. This means first you subtract 32 from the Fahrenheit temperature, then multiply the answer by five ninths.
This works because the Fahrenheit and Celsius scales have different zero points and increments. Fahrenheit sets the freezing point of water at 32°F, Celsius at 0°C. The ratio of each degree differs, so the multiplication by 5/9 adjusts for that.
For example, converting 75°F to Celsius:
- Subtract 32: 75 − 32 = 43
- Multiply by 5/9: 43 × 5/9 = 23.8889°C
Conversion Example
- 100°F to Celsius:
- Subtract 32: 100 − 32 = 68
- Multiply by 5/9: 68 × 5/9 ≈ 37.7778°C
- 60°F to Celsius:
- Subtract 32: 60 − 32 = 28
- Multiply by 5/9: 28 × 5/9 ≈ 15.5556°C
- 45°F to Celsius:
- Subtract 32: 45 − 32 = 13
- Multiply by 5/9: 13 × 5/9 ≈ 7.2222°C
- 85°F to Celsius:
- Subtract 32: 85 − 32 = 53
- Multiply by 5/9: 53 × 5/9 ≈ 29.4444°C

Conversion Definitions
Fahrenheit: Fahrenheit is a temperature scale used mainly in the United States, its zero point is defined by a mixture of ice, water, and ammonium chloride. Water freezes at 32 degrees Fahrenheit and boils at 212 degrees on this scale, dividing the range into 180 equal parts.
Celsius: Celsius is a metric temperature scale, where zero degrees marks the freezing point of water and 100 degrees marks its boiling point under standard atmospheric pressure. It is used worldwide for scientific and everyday temperature measurement.
Conversion FAQs
Why do we subtract 32 when converting Fahrenheit to Celsius?
Subtracting 32 adjusts for the offset between the two scales. Fahrenheit’s zero point is not the same as Celsius’s zero. The 32 represents where water freezes on the Fahrenheit scale, so removing it aligns the temperature to a zero baseline before scaling.
Can I convert Fahrenheit to Celsius mentally?
You can estimate mentally by subtracting 30 and dividing by 2, but this is rough. For example, 75°F minus 30 is 45, divided by 2 is about 22.5°C, close to the exact 23.9°C. Precise calculation needs the full formula.
What happens if I forget to multiply by 5/9?
If you skip multiplying by 5/9, the conversion will be wrong. Subtracting 32 alone only shifts the scale, but does not change the size of each degree. Without scaling, the temperature will be inaccurate and misleading.
Is the conversion formula different for negative temperatures?
No, the same formula applies even for negative Fahrenheit temperatures. Subtract 32 and multiply by 5/9 regardless of positive or negative inputs; the math works consistently across all values.
Why does the Celsius scale have 100 degrees between freezing and boiling?
The Celsius scale was designed around water’s phase changes at standard atmospheric pressure. Dividing the range into 100 equal parts makes it decimal-friendly and easier to use in scientific calculations compared to Fahrenheit’s 180 divisions.
