When the hell we will be able to define a kilogram?

Well??

>metrology
sorry about ur autism

We should define the kilogram in terms of the gravitational constant, just like we used the speed of light to define the metre.

why not some huge multiple of something like the resting mass of an electron

A kilogram is 1000 grams.

proof?

Someone needs to destroy all the chunks of stuff we use to define the kilogram, this way those mad old tenured men in white lab coats will have to come together again to pick a new chunk of stuff as the default kilogram, or maybe decide to use something less arbitrary that can be tested anywhere.

Kilo means 1000, so logically a kilogram is 1000 grams.

what are grams

Probably never.

Good luck piling up electrons for scale calibration in any remotely useful weight range

weight measuring units

1 thousandth of a kilogram.

Just time 1/9,81th of a second cause things fall at 9,81 kg/s

>Weight measurement

I think you mean mass measurement.

I think we should define a gram instead.

depends on the action of the mole

>the defined base unit for mass is kilogram
>not gram
metric was a mistake

AUUUUUGH

They're already building another one, using Avogadro's constant.

1 ml of water weights 1 gram and need 1 J to rise of 1K in heat.

This is an approximation its not actually true

>Well??

One mole of carbon 12 is 12 gram. Extrapolate from there.

>he doesn't know about pound-moles

this

This is likely not to be the primary definition of the kilogram. However, the operationalization is no longer going to be the definition, so they are going to allow for multiple "official" ways of measuring each unit. This may be one of them.

oops not that one, this one:
