-38 degrees Celsius = ? degrees Fahrenheit
1.8 times C plus 32 equals F equivalent.
-68.4C plus 32 equals -36.4F
Why does this look wrong?

Oops [b]DAMN BRACKETS[/b]
-38 C = -36.4 F
MY BAD!

[url]http://students.washington.edu/kyle/temptable.jpg[/url] has a temperature conversion formula table.

and from some other site

To convert a Fahrenheit temperature into Celsius:

Tc = (5/9)*(Tf-32)

For example, to convert a Fahrenheit temperature of 98.6 degrees into degrees Celsius first subtract 32 from the Fahrenheit temperature to get 66.6. Then you multiply 66.6 by five-ninths to get 37 degrees Celsius.

To convert a Celsius temperature into degrees Fahrenheit:

Tf = ((9/5)*Tc)+32

I don't have ANY calculator with me.  That alone is substantially irritating.
This book did not show that I had to drop the signs during the conversion process, then put them back when the answer was found.

Uh no, DoubleFeed, you were right the first time.  -38 degrees C = -36.4 degrees F.  I don't know why that looks wrong to you.  The scales are equivalent at -40 degrees, so that answer makes sense.

Double feed, that looks right to me...

Tf=(9/5)*Tc+32
Tf = Temp in F
Tc = Temp in C = -38

Tf = (9 / 5)* -38 + 32

Tf = -36.4 degF

It looks wrong to me because the numbers are so far apart on the hot side of the freeze point.

you were right, my bad, stupidass parenthesis...

I forgetted that you has to put parenthesises around a negative numba duhh....! (On my calculator that is)

Thank y'all.  I guess I can relax now [BD]  I get really irked when I am doing something wrong and I can't find it.  Good to know I wasn't doing something wrong.
