Hi All here is an easy way to convert Centigrade (C)to Fahrenheit (F) in your head quickly and it's very accurate..
Take the C and multiply it by 2, then minus 10% of that number, then add 32 on and that gives you F.
Example:
25C x 2 = 50. Minus 10% which is 5 = 45. Add 45 + 32 = 77F
30C X 2 = 60. Minus 10% which is 6 = 54. Add 54 + 32 + 86F
