This digital online calculator is designed to convert Fahrenheit to Celsius. To perform the calculation, just enter the temperature in Fahrenheit you want to convert. The conversion to Celsius will be done automatically.
The process to use the Fahrenheit to Celsius calculator would be:
- Select origin unit: By default, the calculator is already set to Fahrenheit degrees, (°F).
- Enter the value: Write the amount of Fahrenheit in the input field.
- Select the conversion unit: By default, the conversion is to Celsius (°C), but you can also select other temperature units (Kelvin, Rankine, etc).
- Get the result: The calculator will automatically show the converted value at the bottom.
How is the conversion from Fahrenheit to Celsius done?
The formula to convert Fahrenheit (°F) in Celsius (°C) is as follows: °C = (°F – 32) × 5/9. If you have a temperature in Fahrenheit, just apply this formula to get the degrees Celsius.
For example:
- To convert 32°F to Celsius, we perform the following conversion operation (32°F – 32) × 5/9 = 0°C.
- To convert 50 degrees Fahrenheit to centigrade degrees (f to c), simply multiply (50°F – 32) × 5/9 ≈ 10°C.
- If you want to convert 68°F to Celsius, the calculation would be quick with (68°F – 32) × 5/9 ≈ 20°C.
- Let’s convert -40 Fahrenheit in Celsius (where Celsius and Fahrenheit are equal): (-40°F – 32) × 5/9 = -40°C.
- For a comfortable room temperature of 72°F, the equivalent in Celsius is: (72°F – 32) × 5/9 ≈ 22.2°C.
Remember that the Fahrenheit degree is a temperature unit of the Imperial System, mainly used in the United States, while the Celsius degree (also called centigrade degrees) is part of the Metric System, used in most countries around the world.
🟧 Note: The Fahrenheit scale, created by the physicist Daniel Gabriel Fahrenheit, sets 32°F as the freezing point and 212°F as the boiling point of water.

Frequently asked questions about converting Fahrenheit to Celsius – FAQ
What is the formula to convert Fahrenheit to Celsius?
The formula is: °C = (°F – 32) x 5/9.
What is the difference between Fahrenheit and Celsius?
Fahrenheit and Celsius are two different temperature scales. Water freezes at 32 °F and boils at 212 °F, while in Celsius, water freezes at 0 °C and boils at 100 °C.
Which temperature scale is more accurate; Fahrenheit or Celsius?
Both scales are equally accurate. The choice of scale depends on the context and region.
How do I quickly convert Fahrenheit to Celsius?
Subtract 32 from the number in Fahrenheit and then multiply by 5/9. For example: If I have 68°F the equivalence would be: 68 – 32 = 36, then 36 × 5/9 = 20°C.
Why do they use Fahrenheit instead of Celsius?
Fahrenheit is common in the U.S. because it was invented by a German in the 18th century and remained as tradition. Celsius is more logical and is used by almost everyone because it is based on water (0°C freezes, 100°C boils).
Is there a quick way to mentally convert Fahrenheit to Celsius?
Yes, for an approximate calculation: subtract 30 from Fahrenheit and divide by 2. Example: 70°F → 70 – 30 = 40, 40 ÷ 2 = 20°C (it’s almost exact, the real one is 21.1°C).
How many degrees Celsius is 98.6°F?
98.6°F is equivalent to 37°C, the normal body temperature. If it rises to 100.4°F (38°C), then you have a fever.
How do I know if it’s cold in Celsius if I only understand Fahrenheit?
32°F is 0°C, the freezing point. If you see 10°C, it’s like 50°F (chilly). If it drops to -18°C, it’s 0°F (freezing!).
How hot is 100°F in Celsius?
100°F is 37.8°C, like a strong summer day or when you have a mild fever. Not comfortable if you’re outside for a long time!
Is Celsius or Fahrenheit better for the weather?
Celsius is easier for the weather because 0°C is freezing and 100°C is boiling. Fahrenheit has larger and less practical numbers (like 32°F for freezing).
How many Celsius is 0°F?
0°F is -17.8°C. That is, very cold, like a freezer or a polar winter.
Which is colder, 0 degrees Fahrenheit or 0 degrees Celsius?
0 degrees Fahrenheit is colder than 0 degrees Celsius. 0 °F is approximately -17.8 °C.
Why is 451°F famous? How much is it in Celsius?
It comes from the book Fahrenheit 451, where books burn at that temperature. It’s 232.8°C, enough to burn paper.
What is the point where the Fahrenheit and Celsius scales intersect?
The Fahrenheit and Celsius scales intersect at -40 degrees. It’s extremely cold, that is, -40 °F is equal to -40 °C.
