Fahrenheit to Celsius Conversions

Fahrenheit
Celsius

Two of the most common temperature scales are the Fahrenheit and Celsius scales.

Fahrenheit was first named after the German physicist Daniel Gabriel Fahrenheit in 1724, while Celsius was named after Swedish astronomer Anders Celsius in 1742.

Since then, the Fahrenheit Temperature Scale and Celsius Temperature Scale have been widely used across the world with Fahrenheit Degrees being the dominant scale in the US, and Celsius being the preferred scale across the rest of the world.

Since these two are the most popular scales for measuring temperature, people often find the need to convert one value into the other.

And while there are many online calculators available online, like ours, there is a simple formula available too that makes converting the value from Fahrenheit to Celsius pretty simple.

But first, look at our online calculator and how to convert Fahrenheit to Celsius.

How to use the Fahrenheit to Celsius (F to C) Calculator?

For a precise calculation, more often than not a calculator proves to be better than a standard celsius conversion chart.

  • Go to the online Fahrenheit to Celsius Calculator
  • Enter the Fahrenheit temp that you wish to convert
  • Click on the Convert button to make the conversion
  • The value will be shown on the Celsius temperature scale
  • If you wish to make another conversion, click on the Reset button

How does the Fahrenheit to Celsius Calculator work?

Across the world, the temperature is measured by using thermometers of different types, and even though there are certain other scales like Kevin that are also used to measure temperature, the most common types are Fahrenheit and Celsius.

The basic difference between the two scales is that the point at which water freezes in Degree Celsius is Zero Degrees and boils at 100 Degrees Celsius.

Meanwhile, water freezes at 21 Degrees Fahrenheit and boils at 212 degrees Fahrenheit.

For this basic difference in the scales, a formula has been devised to make the conversion.

The formula is as follows:

°C = 5/9 × (°F - 32)

Here, °C denotes the temperature in Degrees Celsius, and °F denotes the temperature in Fahrenheit. To make the conversion, simply subtract 32 from the temperature in Fahrenheit, multiply this value by 5, and then divide it by 9.

The figure you get is the temperature in Celsius.

For example:

°C = 5/9 × (°F - 32)

°C = 5/9 × (°68 - 32)

°C = 5/9 × (°36)

°C = 20°C

Therefore, °68 F is equal to 20°C.

Of course, you can use the same formula to convert celsius to Fahrenheit! Simply input the known temperature units into the conversion formulas, and you can get your answer in degrees Fahrenheit or degrees Celsius as the case maybe!

Frequently asked Questions To Convert Temperatures from Fahrenheit Scale into Celsius Scale

What is the formula to convert Fahrenheit to Celsius?

Since the difference in the temperature value at which water boils and freezes is different (Zero degree Celsius being the freezing point of water.

On the other hand, 100 degrees is considered as the boiling point of water – 21 degrees Fahrenheit for freezing and 212-degree Fahrenheit for boiling), a simple formula has been devised to make the conversion. The formula is as follows:

°C = 5/9 × (°F - 32)

°C = 5/9 × (-78.2° - 32)

°C = 5/9 × (-110.2°)

°C = -61.22°C

Therefore, -78.2 °F is equal to -61.22°C.

Why is converting Fahrenheit to Celsius more complicated than what meets the eyes?

Both Fahrenheit and Celsius are offset scales, which means that their starting value is not measured at zero. Besides that, a different additional value is added to every unit of heat making it slightly more complicated to arrive at a simple formula.

Still, the above-mentioned formula has been observed to give near-perfect results.

While the formula to convert Celsius into Fahrenheit is F = C X (9/5) + 32, the formula to make the conversion the other way round is °C = 5/9 × (°F - 32)
