Conversion of 75 degree Fahrenheit to degrees Celsius is determined by the unit size of these two scales.

## 21.111 degrees Celsius(°C)

Conversion of 75 degree Fahrenheit to degrees Celsius is determined by the unit size of these two scales. Celsius is an SI derived unit that measures temperature expressed as (°C) while the Fahrenheit scale also measures temperature but is mostly used in the United States. The only difference between the two scales is that they start with different numbers and rise gradually at different rates.

The Fahrenheit and degrees Celsius are defined by two fixed points. When the Fahrenheit scale shows a temperature reading of 70 °F, it will be 21.111°C on the Celsius scale. This gives a difference of 100 and 180 degrees apart in the unit size of Celsius and Fahrenheit scales respectively.

To determine the calculation of 70 degrees Fahrenheit to degrees Celsius;

180/100 can be simplified as 9/5 whereas 100/180 can be simplified as 5/9.

If you want to get the temperature in degrees Celsius, we subtract 32 from the temperature reading in degrees Fahrenheit. Multiply by 5/9 to determine the reading.

### Fahrenheit to Celsius Converter

#### `70 degrees Fahrenheit(°F) = 21.111 degrees Celsius(°C)`

##### Formula

70°F = 21.111°C is the standard principle used in the conversion. Therefore, it implies that the 70 degrees Fahrenheit is equivalent to 21.111 degrees Celsius.

T (°C) = [T (°F) – 32] x 5/9 is the method for converting degrees Fahrenheit to degrees Celsius.

##### For example;

Convert 70 degrees Fahrenheit to degrees Celsius.

##### Solution

T (°C) = [70°F– 32] x 5/9

= 21.111° Celsius

#### Other methods that work

We can also use a different procedure to determine the results. First, you will add 40 to 70 degrees Fahrenheit and then multiply by 5/9. Add 40 to the result to get the temperature in degrees Celsius.

##### For example;

Convert 70 degrees Fahrenheit to degrees Celsius

##### Solution

70°F + 40 = 110

= 110 X 5/9 = 61.111

= 61.111 - 40 = 21.111° Celsius
