How to Convert Fahrenheit to Celsius (°F to °C)?

The conversion from Fahrenheit to Celsius is straightforward: one degree Fahrenheit equals one degree Celsius multiplied by 5/9, minus 32. Therefore, to perform the conversion, simply subtract 32 from the temperature in Fahrenheit and multiply the result by 5/9.

Formula

This formula represents the conversion from Fahrenheit to Celsius by subtracting 32 from the Fahrenheit value and then multiplying the result by 5/9.
Celsius=(Farenheit32)×59\text{Celsius} = (\text{Farenheit} - 32) \times \frac{5}{9}

Conversion Example: Fahrenheit to Celsius

With these steps, you can easily convert degrees Fahrenheit to Celsius without the need for a calculator. Below, we provide practical examples to better understand the process.

Example 1

Convert 77 degrees Fahrenheit to Celsius.

This example shows how to convert 77 degrees Fahrenheit to Celsius. To do so, subtract 32 from 77, obtaining 45, and then multiply the result by 5/9. This results in 25 degrees Celsius.
Celsius=(7732)×59=25°C\text{Celsius} = (77 - 32) \times \frac{5}{9} = 25\,\text{°C}

Result: 77 degrees Fahrenheit equals 25 degrees Celsius.

Example 2

Convert 14 degrees Fahrenheit to Celsius.

This example shows how to convert 14 degrees Fahrenheit to Celsius. To perform the conversion, subtract 32 from 14, obtaining -18, and then multiply the result by 5/9. This results in -10 degrees Celsius.
Celsius=(1432)×59=10°C\text{Celsius} = (14 - 32) \times \frac{5}{9} = -10\,\text{°C}

Result: 14 degrees Fahrenheit equals -10 degrees Celsius.

Frequently Asked Questions

How to convert Fahrenheit to Celsius?

The formula to convert degrees Fahrenheit (F) to degrees Celsius (C) is: C = (F - 32) × 5/9

What is the conversion for some common Fahrenheit to Celsius values?

  • 32 °F = 0 °C (water's freezing point)
  • 68 °F = 20 °C (typical room temperature)
  • 100 °F = 37.78 °C (approximately body temperature)
  • 212 °F = 100 °C (water's boiling point)

Why are there different temperature scales?

The Fahrenheit scale was developed first, but the Celsius scale is more intuitive because it is based on natural points (freezing and boiling of water). The adoption of one scale or another depends on the region or context.
