What is 40 Degrees Celsius in Fahrenheit? is among the common questions students generally encounter in exams. When students learn about temperature, they come across terms like "Celsius" and "Fahrenheit," which are used to tell how hot or cold something is. So, upon conversion, 40 degrees Celsius in Fahrenheit is 104 degrees.
Learning about both scales is useful in daily life because they are used mostly while reading weather reports, science, and even cooking. So, to understand how to convert 40 C in fahrenheit, keep reading.

Celsius and Fahrenheit Scale Highlights
Before learning how to convert 40 C in Fahrenheit, it is important to understand some key points about both temperature scales. Celsius (°C) and Fahrenheit (°F) are two different ways to measure temperature.
-
On the Celsius scale, water freezes at 0°C and boils at 100°C.
-
On the Fahrenheit scale, water freezes at 32°F and boils at 212°F.
-
Celsius is commonly used in most countries, including India.
-
Fahrenheit, on the other hand, is mainly used in the United States.
-
While both scales are used for the same purpose, which is to measure temperature, the numbers are different.
Formula to Convert 40 Degrees C to F
In order to change Celsius to Fahrenheit, we use a simple formula. The formula to convert 40 degrees C to F is: °F = °C × (9/5) + 32.
Here, C is the value in Celsius and F is the value in Fahrenheit. By putting 40 in the place of C, we can easily find the Fahrenheit value. This formula works for any Celsius temperature you want to convert.
How To Convert 40 Celsius to Fahrenheit?
Now that you know the formula for conversion between Celsius and Fahrenheit scales, to change 40 Celsius to Fahrenheit, you just need to follow these steps:
-
Step 1: Use the formula: F = °C × (9/5) + 32.
-
Step 2: Put the given value of Celsius (C = 40) in the formula: F = (40 × 9/5) + 32
-
Step 3: Solve the multiplication: 40 × 9/5 = 72
-
Step 4: Add 32: 72 + 32 = 104
Therefore, the answer to the question “What is 40 Degrees Celsius in Fahrenheit?” is 104°F.
Shortcut Method to Convert 40 Degrees Celsius in Fahrenheit
There is one more method to convert 40 degrees C to F without directly using the formula. Let us use this method to find what 40 degrees Celsius in Fahrenheit equals:
-
Step 1: Add 40 to the Celsius value: 40 + 40 = 80
-
Step 2: Multiply by 1.8 (or 9/5): 80 × 1.8 = 144
-
Step 3: Subtract 40 from the answer: 144 − 40 = 104
So, using this shortcut method, we get that 40 C in fahrenheit is = 104°F.

What is 40 Fahrenheit in Celsius?
After learning the conversion of 40 C in F, let's now understand how to convert 40 Fahrenheit in Celsius.
-
To convert 40 Fahrenheit in Celsius, use the formula: C = (F − 32) × 5/9
-
Now, put the value of F, which is given as 40 in the formula: C = (40 − 32) × 5/9
= 8 × 5/9
= 40/9 ≈ 4.44°C
Therefore, 40 Fahrenheit in Celsius is almost equal to 4.4°C.
Common Temperatures in Celsius and Fahrenheit
To understand the relation between Celsius and Fahrenheit in a better way, check out some common temperatures that we see in daily life.
-
100°C is equal to 212°F: This is the boiling point of water.
-
37°C is equal to 98.6°F: This is the normal human body temperature.
-
0°C is equal to 32°F: This is the freezing point of water.
-
Around −17.8°C is equal to 0°F: This is a temperature we feel on a very cold winter day.
-
−40°C is equal to −40°F: This is the point where both Celsius and Fahrenheit scales meet.
