World's Heaviest Weight

How do you measure big forces accurately? By calibrating your force transducer on the world's biggest weight - 1,000,000 pounds of force. This machine ensures planes don't break apart, jets provide required thrust, and rockets make it to their destination.

Thanks to the people at NIST for showing me around: Rick Seifarth and Ben Stein. Animations here are by Sean Kelley and additional footage by Jennifer Lauren Lee.

Before visiting NIST in Washington DC I had no idea machines like this existed. Surely there's an accurate way to measure forces without creating such a huge known force?! Nope. This appears to be the best way, with a stack of 20 x 50,000 lb masses creating a maximum force of 4.45 MN or 1,000,000 pounds of force. I also wouldn't have thought about all the corrections that need applying - for example buoyancy subtracts about 125 pounds from the weight of the stack. Plus the local gravitational field strength must be taken into account. And, the gravitational field varies below grade. All of this must be taken into account in order to limit uncertainty to just five parts per million (.0005%)

Who the hell still uses pounds inches etc hmm wait 2 country’s in the whole world one is America and one is near Burma a 3rd world country.

May I chuck it at my enemies?
Finn The Human
i bench that.. too easy
bobby boucher
so what impact those this have on the ground under ?
ricky fleming
Why is america so backwards with weights lbs are old school just tell us in kilos and grams or dont bother at all
TheRealGuy
Still lighter than the Z sword gohan used
Sodium Hydroxide
Imagine these weights being made out of pure osmium.
David K.
Now the real question [only for the smartest/intelligent rest of the world], how many kilograms is that?
Envy Skates
Do u even lift bro?
The Game Achiever
Ugh...I ready need to go to college
Fosi94
So a rocket is basically 33M apples.
BIG DYLO
I wanna take it to the scrapyard.
Spoods
Brad Castleberry could lift that
Cameron Polite
I want enough apples to be equall to the amount of power in a jet engine
Rox
I like rick....he's a cool mofucka and don't even know it...
Owen Pidcock
If you are interested in this then look up the Schwerbelastungskörper. It is a mega weight built by Nazi engineers. You can still go and see it in Berlin.
Scott Penfold
lol pound as mass

Hold my Diet Dr.Kelp

This weight is just waiting for Dom Mezzetti to come and curl it.
The Loobis
I still don't know what the hell it's used for
ElectricTRex Stringer
I want one

Do you even lift bro?
sourpatchghostly
Imagine the whole machine snaps and it falls
Jayxi
I can weight lift that
Geloskie
Niggas talking about flamboyant and Cambodian masses and I barely know how to do Algebra lmao
OnTheGrind
Awesome video!
omartheodd
Weight a moment... why does this exist again?
Сергей Сорокин
this stupid assfuck POUNDS. How do i even undestand that?
Rob B
thats nothing that's my warm up

#liftgoals
Toaster Burns
This guys sounds half way between idubbbz... and idk
frank awesomepants
I can bench that
Sarcalogos Tortolero
Do you even lift bro
Medic Bag
But can I lift it brah
ED
Had to go to my calculator to approve of the math. It's approved

LBS of Mass? LBS of weight. KG is Mass and N is Force in physics.
Back Up
Hydraulic press will still crush it though 😆
TEDDY DUANE
this is where chuck norris works out
SB Goku
I bench pressed it.
KG3N Golden
Put a piece of coal see what happens, I don't even know if it could even turn into a diamond tho.
Liquido Suave
Goku should use those as dumbbells
helenHTID
That's a one arm bench press for me all day
fischele
Adding to the list at the beginning of the video: if you fall of the parallel bars in PE, you're expiriencing about 24 kN. Yes, I'm one of the nerds who calculate such stuff.

over attachment to these machines is keeping the US to embrace the metric system.
