Read an article about how to have a safe summer cookout. Ground beef should have an internal temperature of 160 degrees F. Ok, since this is a science teacher blog, what temperature is 160 degrees F in C? No cheating, do not copy and past 160 degrees F in Google and key in the word convert. Get out your slide rule and make the conversion. Oh, too young to even know what that is, too bad.
A way that you will never forget just remember that 0'C = 32'F
0'C + 1'C = 32'F + 1.8'F = 33.8'F
0'C + 2'C = 32'F + 2(1.8)'F = 35.6'F
0'C + 3'C = 32'F + 3(1.8)'F = 37.4'F
and so on.
If you want to change take 23'C into 'F
0'C + 23'C = 32'F + 23(1.8)'F = 73.4'F
thus the formula to convert 'C to 'F is as following
x'C = 32'F + x(1.8)'F
Let us work back
0'C + x'C = 32'F + x(1.8)'F = 73.4'F
do it your self and find the value of x
you will get another formula that converts 'F to 'C
