To convert from Fahrenheit to centigrade, I think we need to change the second step. Instead of adding tenths we have to add ninth’s.

63 F –> according to the steps in the video

63-32 = 31 –> 31+3(tenth of 31) = 34 –> 34/2 = 17 but actual answer is 17.2.

Instead if we add 3.4 which is the ninth of 31, we will get 17.2.

63-32 = 31 –> 31+3.4 = 34.4 –> 34.4 / 2 = 17.2 centigrade

Similarly 147.2 F –> 115.2 + 12.8(ninth of 115.2) = 128 / 2 = 64 C

141.8F –> 109.8 + 12.2 –> 122 –> 61 C

So the steps to convert F to C could be 1. subtract 32, add ninth, halve.

Please correct if you see any flaw here. Thank you
