I love video’s from Veritasium.
In this video we are introduced to the world’s heaviest (calibrated) weight.
How well calibrated? On a total weight of 1.000.000 pound, they guaranty a maximum variation of 5 pounds….
You can find this contraption at NIST (National Institute of Standards and Technology)

Also in this series a visit to the American Kilogram. As an European I find it funny that the American Pound starts off as a Kilogram 🙂

And while we are at it, I would like to also show you “the world roundest object”.
Fascinating stuff!

I bet you’re hooked on Veritasium too now!
