    Ive seen very similar analytics balances that work very similarly to this one. It uses a variable capacitor to change frequency once the mass is zeroed out, the plate is moved by a precise current source on a magnetic field.Then that value is given aa the mass measurement. The lab ones are accurate to plus or minus 3 nanograms. One amusing side note is they use a polonium 210 ionization source to eliminate static charge on the weiging boat and the sample. ❤

      @@TomasJknOnYT The kg no longer depends on g! g is was used in the calculations because the kibble balance measured the object’s weight in our gravitational field (weight=mass x gravity) so we had to divide by g to get the proper mass. Another way to think of it is that by measuring the mass of the IPK on Earth, we naturally introduce dependence on our gravity, so we had to do the extra work of precisely measuring g and dividing by it to cancel out the non-universal earth gravity effect.

      That is true, but it would be nicer to somehow rearrange the experiment in such a way that the measurement of g is tied to the measurement of v - so that we do not need a separate measurement (in the same manner as this experiment avoids measurement of L). Or ditch dependence on gravitational effect of the mass and rely only on inertial effect of the mass

      Good question! The meter and second are defined by different constants of nature. The meter is defined by the speed of light and the second is defined the frequency of a particular caesium atom. So it actually takes all three constants to define the kilogram (but Planck's constant is the one specifically relavant to the kilogram here)

The various Inches were unified in the 1800s, many years *after* the French introduced metric (1700s). They were unified almost by accident, when Johansson (seller of gauge blocks) decided (all by himself) that orders for Inch gauge blocks would be fulfilled with the conversion factor of 25.4 mm = 1 Inch exactly. He didn't ask anyone. He didn't inform anyone until someone later asked. It took metric to unify the Imperial Inches.
