all I know is

1 mile = 1.6km
1lb = 16oz = 1 pint
1yr = 3ft
2pint = 1quart
8pint = 1gallon

1ton = 2000lb

1in = 2.5cm
1m squared = 10.76 feet squared

1gallon = 3.785 l

32f = 0C
212F = 100c

1lb = 0.453kg
1 oz = 28g
1kg = 2.2lb

is there any more i need to know?

Which of the following compounds will have its proton(s) shifted furthest and downfield on a 200 MHz 1H NMR spectrum?

A. CH3CH3
B. CH3CI3
C. CH3I
D. CH2I2
E. CHI3

isn't it B? cuz Cl is more electronegative than I ?

look a little closer. B says CH3CI3 - that's an I and not an L.

EDIT: LOL i guess you changed your question. sorry, ignore my post

instead of memorizing those numbers memorize this formula:

F = (9/5) C + 32
