How to Convert Temperatures Between Fahrenheit and Celsius

Converting between Fahrenheit and Celsius temperature scales is a common need, especially when traveling or reading material written for an audience using a different system. Fahrenheit is more commonly used in the United States, while Celsius is the standard system for most other parts of the world. Both scales link to benchmarks based on water, but use a different zero point and degree sizes. This guide will provide the key basics for converting Fahrenheit to Celsius and vice versa.

The Difference Between the Scales

The Celsius scale, also known as centigrade, sets the freezing point of water at 0 degrees and the boiling point at 100 degrees. The Fahrenheit scale sets 32 degrees as the freezing point of water and 212 degrees as the boiling point, at standard atmospheric pressure. So a degree Celsius represents a larger temperature change than a degree Fahrenheit.

This table summarizes the differences:

Description Celsius Fahrenheit
Freezing Point of Water 32°
Boiling Point of Water 100° 212°
Degree Size Equal fractions of difference between freezing and boiling points Smaller fraction of same range

Converting Temperatures

To convert a temperature from Fahrenheit to Celsius, subtract 32 and multiply by .5556 (or 5/9). The formulas look like:

Celsius = (Fahrenheit – 32) x .5556 Fahrenheit = (Celsius x 1.8) + 32

Some examples converting common reference temperatures:

  • 98.6°F (normal human body temperature) = 37°C
  • 80°F (room temperature) = 26.7°C
  • 42°F (cool winter day) = 5.6°C

Key Takeaways

These are the essential points for converting temperatures between Fahrenheit and Celsius:

  • Celsius sets 0° at water’s freeze point and 100° at the boiling point
  • Fahrenheit sets 32° at freezing and 212° at boiling instead
  • Use the equations Celsius = (Fahrenheit – 32) x .5556 and Fahrenheit = (Celsius x 1.8) + 32
  • Celsius uses bigger degrees so a 5 degree change is greater than 5 degrees Fahrenheit
  • Know some common converted temperatures like body temp (37°C) and room temp (26.7°C)

The table, formulas, and examples provide the key tools needed to interconvert temperatures. Just plug numbers into the equations to easily shift between Celsius and Fahrenheit.

How to convert Fahrenheit to Celsius

0 degrees Fahrenheit is equal to -17.77778 degrees Celsius:

0 °F = -17.77778 °C

The temperature T in degrees Celsius (°C) is equal to the temperature T in degrees Fahrenheit (°F) minus 32, times 5/9:

T(°C) = (T(°F) – 32) × 5/9

or

T(°C) = (T(°F) – 32) / (9/5)

or

T(°C) = (T(°F) – 32) / 1.8

Fahrenheit to Celsius formula

℃=(℉-32)/1.8

Example

Convert 50 degrees Fahrenheit to degrees Celsius:

T(°C) = (50°F – 32) × 5/9 = 10 °C

Convert 68 degrees Fahrenheit to degrees Celsius:

T(°C) = (68°F – 32) × 5/9 = 20 °C

Convert 70 degrees Fahrenheit to degrees Celsius:

T(°C) = (70°F – 32) × 5/9 = 21.11 °C

Convert 80 degrees Fahrenheit to degrees Celsius:

T(°C) = (80°F – 32) × 5/9 = 26.67 °C
