1N = force required to accelerate a mass of one kilogram at a rate of one meter per second squared.
But he asked for a demonstration . . . ;D

OK mister smarty pants; what does this equal:

Newton-meters per second squared?

And how many are now missing in Fukushima?

Watts

4.7 GWe

nanny, nanny, boo boo!   ;)

(says the guy with 15 years of power plant experience)

Oops, divided by one too many seconds.  
Watts are Joules per second or kg-meters squared per second cubed, which makes it Newton-meters per second.
So nanny nanny it's my boo boo. :-[
My engineering physics professor would be disappointed.  He pummeled us mercilessly with derived units and units conversions.

Guess I was having a Shaq moment...  (does Shaq drink Bigfoot?)

Ok in laymans terms I still need a demonstration to understand
1vertical<<<<<dense

Edit: 22000 missing or dead in the Fukushima events
Edit again: This number is probably for all of Japan...sorry for the confusion

Wait, what? What happened? I can't find this story anywhere.

So what is a W/s, and what is it used for?

Is that for Japan or just Fukushima?

Do you need someone to push you? ;D  What kind of demonstration are you looking for?  It's more confusing in English units when you start talking about lbs-force.

1 N = 1 kg m/s^2

The acceleration due to gravity is G = 9.81 m/s^2, so 1 N/G  = 1/9.81 kg, or ~102 grams, which is ~3.6 ounces.  This means 1 Newton is the force required for you to keep 3.6 ounces from falling, and ~3 Newtons might have been needed for Isaac to hold the apple that hit his head (assuming it was an average eating apple, there's a lot of slop there ;D ).

You are right Tom I think that is for all of Japan....

Guilty :)

I had a friend named Julia.  Everybody called her Jules, so I called her Newton Meters.  Everyone that was nerdy, but Julia liked it.

The missing I was asking about is the lost generation capacity at the Dai-ichi facility.

4.7 GW. =  4,700,000,000 Watts

That's almost enough power for 4 flux capacitors!

Yeah, what's that in Jigawatts?
