how would I calibrate a scale to 1 kilogram using the planck constant if I had nothing else to use?

2.62K views

I read an article about tying the weight of a kilogram to the planck constant rather than Big K. I understand in principle using a mathematical equation to define the kilo using what we believe to be an unchanging constant force, as opposed to a man made object that will decay, or lose weight over time. What I don’t get is how I would use that equation to then calibrate an actual scale, or guage the weight of an actual physical object if all I have is the equation.

You don’t. Unless you’re trying to do ultra precise measurements your scale’s margin of error is by many orders of magnitude greater than the precision that the new measurement gives you.
