Winter is a season that brings snow, ice, and cold temperatures. It's not uncommon to hear people talk about how cold it is outside, with some even saying that it's minus 40 Fahrenheit. But what does that mean in Celsius? In this article, we will explore what minus 40 Fahrenheit is in Celsius and how cold it really is.
What is Fahrenheit?
Fahrenheit is a temperature scale used in the United States and a few other countries. It was created by a German physicist named Daniel Gabriel Fahrenheit in the early 18th century. The Fahrenheit scale is based on water's freezing and boiling points, with 32 degrees Fahrenheit being the freezing point of water and 212 degrees Fahrenheit being the boiling point of water at sea level.
What is Celsius?
Celsius, also known as centigrade, is a temperature scale used in most countries around the world. It was created by a Swedish astronomer named Anders Celsius in the mid-18th century. The Celsius scale is based on water's freezing and boiling points, with 0 degrees Celsius being the freezing point of water and 100 degrees Celsius being the boiling point of water at sea level.
How to Convert Fahrenheit to Celsius
To convert Fahrenheit to Celsius, you can use the following formula:
Celsius = (Fahrenheit - 32) x 5/9
So, if we want to convert minus 40 Fahrenheit to Celsius, we can plug in the value:
Celsius = (minus 40 - 32) x 5/9 = -40
How Cold is Minus 40 Fahrenheit in Celsius?
Minus 40 Fahrenheit is equivalent to -40 Celsius. This temperature is so cold that it's hard to imagine unless you've experienced it yourself. At this temperature, exposed skin can freeze within minutes, and frostbite can occur within seconds. It's important to dress warmly and stay indoors as much as possible when the temperature drops this low.
Other Extreme Temperatures

Minus 40 Fahrenheit is not the only extreme temperature that people might experience. Here are a few other examples:
- Minus 129 Fahrenheit is the coldest temperature ever recorded on Earth, which occurred in Antarctica in 1983.
- Minus 88 Fahrenheit is the average temperature on the surface of Mars.
- Minus 452 Fahrenheit is absolute zero, the temperature at which all matter would theoretically stop moving.
- Minus 320.4 Fahrenheit is the boiling point of liquid nitrogen.
Conclusion
Minus 40 Fahrenheit is equivalent to -40 Celsius, a temperature that is incredibly cold and potentially dangerous. It's important to take precautions and dress warmly when the temperature drops this low. By understanding how to convert Fahrenheit to Celsius, we can better understand the temperature outside and how to prepare for it.
