Fahrenheit to Celsius is a conversion that carries huge significance. Fahrenheit and Celsius refer to the scales which are used for measuring and reporting of temperatures. Moreover, these scales can measure the room, air, and water temperatures. The use of the Fahrenheit scale takes place in the United States. In contrast, the Celsius scale is famous worldwide. The vast majority of the world, with the notable exception of the United States, makes use of the Celsius Scale. It is certainly important for scientists to know how to convert the Fahrenheit scale to the Celsius scale. Learn Fahrenheit to Celsius formula here.

What is Fahrenheit and Celsius

The Fahrenheit scale was named after the German physicist Daniel Gabriel Fahrenheit. It makes use of the degree Fahrenheit symbol: “F” as the unit. The lower defining point, 0 ℉, of this scale is the freezing temperature of a solution of brine.

This solution of brine comprises of ice, water, and ammonium chloride. Moreover, the melting point of ice on this scale takes place at 32 ℉. Furthermore, the boiling point of water on this scale is 212 ℉.

The Celsius scale refers to a temperature scale that is used by the international system of units (SI). It is popular almost everywhere in the world except the United States and a few other places. The degree Celsius symbol °C can refer to a particular temperature on this scale. The scale is named after Anders Celsius who was a Swedish astronomer.

Most noteworthy, the freezing point of water on this scale is 0 °C, while the boiling point of water is 100 °C. Furthermore, this takes place at 1 atm pressure. Sometimes, the Celsius scale is also called the centigrade scale.

Fahrenheit to Celsius Formula

One certainly requires a formula for converting the Fahrenheit scale to the Celsius scale. Moreover, this formula is below:

C = 5/9 x (F-32),

Where, C = Celsius measure and F = Fahrenheit measure.

Fahrenheit to Celsius formula

After knowing the formula, one can convert the Fahrenheit scale to the Celsius scale. Moreover, there are three steps for achieving this which are as follows;

1. First of all, subtract 32 from the Fahrenheit temperature.

2. Multiply this particular number by five now.

3. Divide the result which is achieved by nine

Fahrenheit to Celsius Formula Derivation ( f to c )

The Boiling point water at the normal pressure measures 100° in Celsius. However, water’s boiling point is at 212° in Fahrenheit.

Also, water freezes at 0° in Celsius. In contrast, the freezing point of water is 32° in the Fahrenheit scale.

When it comes to the freezing point of water, the scales start at a different number (0 vs 32), so one would need to add or subtract 32.

When it comes to the boiling point of water, scales rise at a different rate (100 vs 180), so here multiplication is necessary.

So, in order to convert from the Fahrenheit scale to the Celsius scale, one needs to first subtract 32. Afterward, one needs to multiply by 100/180.

Above all, 100/180 can be simplified to 5/9. This certainly is an easier way.

Hence, the formula for converting Fahrenheit to Celsius scale becomes:

C = 5/9 x (F-32).
