1/2 inch drills will hold a larger bit.
They are typically more powerful as well.

Oh about an 1/8 of an inch. In chuck size that is. Also generally 1/2 inch drills run about 1/2 the rpm of 3/8 inch drills.

1/2 inch drill is often considered a heavy duty drill as it will accept larger size drills and it is usually built with more power.
Drill bits are interchangeable on these, except the larger drill bits accepted by a 1/2" drill will not fit on a 3/8" drill.
You can still get pretty large bits to fit on the smaller drill -- the bit will be manufactured with a thinner shaft to fit the smaller drill.
The most common homeowner used drill is 3/8".
It is also the size commonly used by professionals -- optimal size, not too heavy, not too large.

3/8 drills are used primarlily for household use and some small projects or where you need a high speed drill for drywall or some diamond bits. They spin most of the time 30-40% faster than 1/2 chuck drills, however they dont have the power to spin the larger bits that usually come in 1/2'' size.
1/2'' chucks are most of the time used for heavey duty drilling like concrete or through 2'' or thicker wood with heavier auger or spade bits.
for everyday use, I would go with a 3/8!

the size opening in the chuck, where the bits go a 3/8" will only accept bits up to that size. A 1/2" will accept bits up to that size and it usually has more power than the 3/8"

Why not stick to the side that just deals in inches and keep your calculationd coherent. I once heard of a metric foot which was because in construction all the woodwrking machines wer designed in imperial and wre so well made it would have been nonsense to scrap them. A house brick was originally made to suit the human hand. imperial relates more to human conceptuality than metric which is better for the scientific. It is dificult ot work with both at once.
