Fascinating. New meaning for "What the h?!"
Curious as to who certifies the parts of the scale for accuracy.

Superfantastically cool....guess now my 2.204 lbs/Kg is going to be useless unless I go to at least 6 decimal places...
Can you imagine explaining this to the current crop of American High School students
Thanks

For those of you with questions that want to get further in the weeds on this; the NIST website has a lot of good information on this very topic.

To answer the question, since electricity is merely the excitement of stationary electrons, electricity doesn't weigh anything.

Taught high school physics for years. This is no more difficult to teach than the SI definition of a meter (defined as the distance light travels in a precise measure of time); or the definition of a second (The second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom.)
Some high school learners get it...others won't. lol
