>Meter is defined as distance the light travels in vacuum in 1/299'792'458th of a second
Very well then. Proceed to represent me exactly one (1) meter using this definition. Note that you cannot use any standard of length, of course. I'm waiting.
This definition is GARBAGE. Better definition is a prototype bar in NTP conditions, or one based on cube of water.

you use time instead of length

there's nothing wrong twith that. it's a physical constant.
thanksfully the Kg is also being re-defined by the plank's constant(As a Chemfag I actually like the Si atom approach, but whatever). so we don't depennd on shitty metal pieces like the OP.

Why don't they just say that the meter is based on an inaccurate measurement of the size of the earth. and at the time they created it and publicized it, they knew it was inaccurate.

The problem is: how do I find out how long a meter is without having a ruler nearby?
The point of OP's definition is that you can measure how far light will travel in 1/299'792'458th of a second, and build your own ruler based on that.
