What's the Easiest Way to Convert Fahrenheit to Celsius? 

 What's the difference between Celsius and Fahrenheit? It's really a quirk of history and a simple mathematical conversion. Learn the easiest way to convert Fahrenheit to Celsius as well as the reverse calculation with simple equations and a chart. 

 Converting Fahrenheit to Celsius 

 Some would consider a quick estimate the easiest way to convert a Fahrenheit temperature to a Celsius temperature. Others want a more precise answer quickly. Here, you can learn both methods.

Fahrenheit to Celsius Estimate Formula Use this formula to get a good estimate of the Celsius temperature when converting from Fahrenheit. In this case / means divided by or to use division.

 (Fahrenheit temp. [F]-30)/2 = Celsius temp. 

In other words, if you’d like to convert a Fahrenheit temperature to an approximate Celsius temperature: 

Start with the temperature in Fahrenheit (e.g., 100 degrees).

Subtract 30 from this figure (e.g., 100 - 30 = 70).

Divide your answer by 2 (e.g., 70 / 2 = 35).

Fahrenheit to Celsius Exact Formula If you want a more precise calculation, you can use the more exact formula. Using this calculation, we determine that 100 degrees Fahrenheit is equivalent to 37.78 degrees Celsius.

(F - 32) / 1.8 = C 

In other words, if you'd like to convert a temperature reading in Fahrenheit to Celsius: 

Start with the temperature in Fahrenheit (e.g., 100 degrees).

Subtract 32 from this figure (e.g., 100 - 32 = 68).

Divide your answer by 1.8 (e.g., 68 / 1.8 = 37.78) 

Converting Celsius to Fahrenheit To convert Celsius to Fahrenheit, simply reverse the equation. In this case * means times, or to use multiplication.

(C * 1.8) + 32 = F 

You can use this equation to show that 100 degrees Celsius is equal to 212 degrees Fahrenheit.

Start with the temperature in Celsius (e.g., 100 degrees). 

Multiply this figure by 1.8 (e.g., 100 * 1.8 = 180). 

Add 32 to this figure (e.g., 180 + 32 = 212).

What's the Difference Between Fahrenheit and Celsius?

If you're from the United States, you're probably accustomed to describing temperature by Fahrenheit. A very hot summer day is 100 degrees, a pleasant spring morning is 50 degrees, and 0 degrees is ungodly cold. If you're from almost anywhere else, you likely favor Celsius, where 0 degrees is only pretty cold, 50 degrees is unspeakably hot, and 100 degrees happens on a stove, not outside.

Are Fahrenheit and Celsius Readings Ever the Same? 

If you were wondering if there is a temperature where Fahrenheit and Celsius are the same, it's at 40 below zero, also known as -40 or negative 40. At all other temperatures, the difference is history.
