I think thats a cool way of doing it “Dan”, your formula isn’t always exact as you say but its very well close enough.
And “Ashley” you say that for every 3 degrees celsius, farenhiet goes up 5 degrees and your almost right but at every 10 intervals Celsius goes up by only 2.

Thanks Guys, learned a lot today

The easiest way for me to get an exact conversion in my head is this:

1. Multiply Celsius by two -> 6 * 2 = 12
2. Subtract 10% of that new number from its self -> 12 – 1.2 = 10.8
3. Add 32 -> 32 + 10.8 = 42.8

Easy peezy!

Getting exact numbers from Fahrenheit to Celsius is not as easy.

your missing the conversion for 15. i needed it for 15, bu thanks for the formula

Posted at 06:48h, 21 Maya thing i learned is that every 3° celcius gos up by every 5° ferinhiet goes up

## Chris Pellbring

Posted at 12:53h, 11 FebruaryYour formula for Celsius to Fahrenheit conversion is wrong.

Should read: Celsius to Fahrenheit conversion: multiply CELSIUS by 9/5 and add 32 degrees

Posted at 21:13h, 12 FebruaryThanks Chris for pointing out the error. I corrected the formula.

## Dan

Posted at 20:10h, 12 AprilI quick math i use in my head from C to F is double it and add 30.

example: 10c x 2 + 30 = 50F. it’s close or exact at times.
