I did google, but I'm still confused.
My table saw draws 15 amps. I have been using a 100 ft 16 gauge extension
cord to run her, but I found out recently that this is to wimpy a cord. My
manual recommends a 12 gauge extension cord not exceeding 50 feet.
My question is if I go to 100 feet of extension cord, is 12 gauge still ok?
I guess do to the voltage drop with the longer cord that I may need a 10
gauge cord?
My original calulations would be valid for 50ft.. I see Mark Hopkins
link agrees. Very handy calculater by the way.

NO ! ! !
As it is, you have a disaster waiting to happen.
I have a 100 ft power cord for my saw, it's 10 ga; however, it is also wired
for 240V service.
If you ever try to rip 8/4 white oak, you will understand why.
For your application, if you decide to use 12 ga anyway, at least operate at
240V.

1) Your calculator is goofy. #10 gives 3%, so I don't know why your
calculator requires #8.
2) 3% is a code requirement for branch circuits. It has nothing to do with
extension cords. As I indicated above, 100' is probably not a good choice,
but if the extension cord is rated for 15a, it is legal.
No. You will need at least a #8 wire. See below.

I would keep a close eye on the heat generated with a cord that long in any
gauge.

The extension cord should say how many amps it can handle. If your 100ft 12
gauge says 15a is okay, you are fine. Since we don't know what the
insulation is made of, we can't really say.
That is just what is safe.
Whether it is reasonable is a whole other story. Unless the outlet is right
next to the panel, 15a is a lot to put through a 100' extension cord; don't
do it unless you have to as it is probably not good for your motor.
Somebody pointed out the voltage drop was not too bad, but he ignored the
voltage drop to the outlet.

I don't know enough about electricity to know if this idea is any good, but
I've wondered about building an extension cord that uses two identical sets
of conductors. The male end could be two plugs. The female ends would
connect to the proper locations on a standard dual outlet. Would this work?

It may be legal, but still might not give good performance at the saw
because of the cumulative voltage drop. (This is based on my
understanding that the cord's rating is protecting the cord, not
guaranteeing full voltage at the appliance.)

Ten years ago I built a 6,000 sq. ft. building using a 120 volt, 1.5 HP
contractor's saw. I used a 12 gauge Romex, 250' extension cord. It didn't melt.
I am still using the same saw/motor. Not a recommendation, just a true
anecdote.

When I built my shop, I used a 50' and a 100' 10 gauge extension cord set to
run 110 volt to my tools, including a table saw rated at 12 amps (Delta
contractor's model). No problems with cord or saw. That was about 7 years ago,
at least when I started.

Make you own cord from 10 GA Romex. Not to exceed 100 ft.

not sure what you're trying to do here, but it won't work ; ^ )
if you're trying to make 220V it won't work because the two
receptacles on the standard dual outlet are just connected together
inside the wall. to get 220 you need to get power from both left and
right sides of the meter panel
if you're trying to get more amps from the standard dual outlet it
won't work because again the dual receptacle is coming from one
circuit.
if you're trying to beat the voltage drop of your light weight cord it
theoretically would work. don't do it... better, cheaper and less
chance for dumb accidents to just go out and buy yourself a commercial
extension cord. if you need more than 50 feet but less than 100 get a
set of ends while you're at it and cut the extra off and make a short
heavy cord with a gang box on the female end. they come in handy.

No ceiling to staple to. I'm running power to a workshop in the backyard.
If I owned this place (I rent) I would run some conduit and permanent power

How about 50 feet of 12 gauge at 110 V ?

If the cord is warm to the touch, it's gauge is too fine.
#10 wire extension would work, but it may be a bit stiff. If you are
consistently in need of the 100' cord, consider putting in a separate
outlet for the saw. A 20 amp circuit would work.
Mostly good stuff here, but 8 is not necessary. The advice to go to 240V is
good. Why not staple a piece of Romex to the ceiling and be done with it.
Portable cordage is very expensive!
12 will do fine at 120V, unless you are running max load or more. At 240V,
12 is more than enough.

I knew that. Yup, 12 is definitely out. 10 is on the edge. 8 would

Here's some numbers for you:
16 ga is 0.4016 ohms per 100 ft. = 6.024 volt drop at 15 amps
12 ga is 0.1588 ohms per 100 ft = 2.38 volt drop at 15 amps
I'd say 12 ga is fine.
