Have you ever wondered how hot 42°C really is in Fahrenheit? Whether you’re traveling, cooking, or checking the weather, converting temperatures between Celsius and Fahrenheit is a useful skill.
In this easy-to-follow guide, we’ll show you:
- How to convert 42°C to Fahrenheit
- What 42°C feels like
- The difference between Celsius and Fahrenheit
- How to use a formula or a calculator
- And more!
Let’s get started with the basics.
🌡️ What is 42°C in Fahrenheit?
To convert Celsius to Fahrenheit, use this formula:
F = (C × 9/5) + 32
Now plug in 42 for C:
F = (42 × 9/5) + 32
F = (75.6) + 32
F = 107.6°F
This is very hot, whether you’re talking about the weather, a body temperature, or an oven setting.
🔥 How Hot is 42°C or 107.6°F?
Here’s how 42°C (107.6°F) compares:
| Context | Temperature | Description |
|---|---|---|
| Body Temperature | 42°C / 107.6°F | Medical emergency (fever) |
| Outdoor Weather | 42°C / 107.6°F | Extremely hot day |
| Oven Temperature | 42°C / 107.6°F | Very low, not suitable for baking |
So yes, 42°C is extremely hot. If it’s your body temp, it’s dangerous. If it’s the weather, stay hydrated!
🧠 Why Use Celsius and Fahrenheit?
Let’s break it down:
✅ Celsius (°C):
- Used in most of the world
- Based on water freezing at 0°C and boiling at 100°C
✅ Fahrenheit (°F):
- Used mainly in the United States
- Water freezes at 32°F and boils at 212°F
That’s why converting temperatures is so important if you’re switching between regions.
📈 Celsius to Fahrenheit Chart (For Quick Reference)
| Celsius (°C) | Fahrenheit (°F) |
|---|---|
| 0°C | 32°F |
| 10°C | 50°F |
| 20°C | 68°F |
| 30°C | 86°F |
| 42°C | 107.6°F |
| 50°C | 122°F |
As you can see, 42°C is well above average room temperature and is considered dangerously hot.
🧮 How to Convert 42°C to Fahrenheit – Step-by-Step
Want to remember how to do it yourself?
Step 1: Multiply by 9
42 × 9 = 378
Step 2: Divide by 5
378 ÷ 5 = 75.6
Step 3: Add 32
75.6 + 32 = 107.6
✅ Final Answer: 107.6°F
This method works for any Celsius to Fahrenheit conversion.
📱 Use Online Tools to Convert 42°C to Fahrenheit
You can use:
- Google: Just type “42°C to F” and you’ll see the answer instantly.

🥵 What If Your Body Temperature Is 42°C?
❗ Warning: This is extremely dangerous.
Normal body temp is:
- 36.5°C to 37.5°C (97.7°F to 99.5°F)
At 42°C (107.6°F):
- The body can’t function properly.
- There is risk of organ failure, brain damage, or death.
- This condition is called hyperpyrexia.
Call emergency services immediately if someone has this high of a temperature.
☀️ What If the Weather Is 42°C?
That’s very hot, especially in:
- Deserts
- Tropical countries
- Summer heat waves
Safety Tips:
- Drink lots of water
- Stay in shade or air conditioning
- Avoid going out in the afternoon
- Wear light clothing
🧊 What Does 42°F Feel Like?
Let’s reverse the situation.
42°F = About 5.5°C
That’s cool, not cold. You may need a jacket, especially in the morning or evening.
🧪 Fahrenheit to Celsius Formula
Want to go the other way?
C = (F – 32) × 5/9
If you’re converting 107.6°F to Celsius:
C = (107.6 – 32) × 5/9
C = 75.6 × 5/9
C = 42°C
✅ It checks out!
