Every time I go to Europe, it takes me forever to really figure out the temperature when I watch the morning news. I thought I would remind everyone of a "quick tip" conversion I learned if you want to know the (approx.) temp every day.
"Double the Centigrade and add 30"
For example,
The Temperature in Centigrade is 18. The approx. Fahrenheit temp would be: 66.
18 x 2 + 30 = 66.
Yes, this is a rough estimate, but I thought it might help someone.
Have a good day. :)
