An Oxford professor has shared a handy trick to completely transform your life when we're all finally free to travel abroad.
If you find yourself in a foreign land and the temperature is in Fahrenheit, a maths expert has shared a way to convert it instantly - and make it readable for your British brain!
The University of Oxford has shared a method of turning degrees Celsius into degrees Fahrenheit via Twitter.
As reported by BirminghamLive Oxbridge boffin, Dr Tom Crawford, who loves numbers so much he's covered in maths tattoos, came up with the hack saying: "Turning degrees Celsius into degrees Fahrenheit. Now there is an exact formula for this conversion.

"But it involves some pretty nasty numbers."
The brainbox, who goes by @tomrocksmaths on Twitter, adds: "So what we are going to do instead is come up with an approximation.
"It might not work for your scientific experiments but if you are on holiday and you just want to know the temperature, it will work a treat.
"To approximately turn degrees Celsius into degrees Fahrenheit, all you have to do is multiply by two and add 30. So let's look at 30 degrees Celsius. Multiply by two to get 60 and add 30 to get 90 degrees Fahrenheit.
"So let's look at 10C- a little cooler. Multiply by two to get 20 and then add 30 to get 10 degrees Celsius is approx 50 degrees Fahrenheit.
"Multiply by two, add 30, and you have it!"
