# Fahrenheit to Celsius Conversion – °F to °C

LAST UPDATE: October 26th, 2020

## Formula – How to convert Fahrenheit (°F) to Celsius (°C)

### Formula 1: Easy to remember

((°F -32) x 5)÷9

• Step 1: Subtract 32 from the temperature in Fahrenheit
• Step 2: Multiply that number by 5
• Step 3: Divide that number by 9

#### Example

Find 60°F in Celsius:

• Step 1: Subtract 32 from the °F: 60 – 32 = 28
• Step 2: Multiply that number by 5: 28 x 5 = 140
• Step 3: Divide that number by 9: 140 ÷ 9 = 15.56°C

### Formula 2: Quicker

(°F – 32) ÷ 1.8

• Step 1: Subtract 32 from the temperature in Fahrenheit
• Step 2: Divide that number by 1.8

#### Example

Find 70°F in Celsius:

• Step 1: Subtract 32 from the temperature in Fahrenheit: 70 – 32 = 38
• Step 2: Divide that number by 1.8: 38 ÷ 1.8 = 21.11°C

## What is the difference between Celsius and Fahrenheit?

Celsius and Fahrenheit are two temperature scales.

Celsius is benchmarked from the freezing point of water (0°C) and the boiling point of water (100°C).

Fahrenheit’s origins are not certain, however it is believed that 0°F was the freezing point of equal parts ice, water, and salt. 100°F was about the body temperature of a person. Today, Fahrenheit is benchmarked from the freezing point of water (32°F) and the boiling point of water (212°F).

## Who uses Celsius and Fahrenheit?

Celsius is a “standard unit” and is commonly used worldwide.

Fahrenheit is used in the United States as well as some regions of the Pacific and the Caribbean.

## What are other common temperature scales?

Kelvin and Rankine are the two other temperature scales. They are benchmarked off absolute 0 (the coldest temperature possible).

Kelvin (°K) increases at the same rate as the Celsius scale, but is offset by 273.15° from Celsius. Absolute 0 is -273.15°C, and 0K.

Rankine (°R) increases at the same rate as the Fahrenheit scale, but is offset by 459.67° from Fahrenheit. Absolute 0 is -459.67°F, and 0°R.
