A MASSive development for every thing that matters

The Kilogram just recently celebrated its 125th birthday on Sept. 22. While this doesn't in itself seem like big news, consider this: the kilogram is currently the only unit in the Système Internationale d'Unités which is still based off of a physical object rather than a concept. While many of you may know that it was first initially theorized as the mass of a liter of water at 4 degrees Celsius (the temperature at which it is most dense) it has been represented by a cylinder of platinum/iridium alloy since September of 1899, and it is this cylinder which we base all our measurements of mass off of, as well as there being several other measurements dependent on the kilogram for their definition as well. The problem with this definition of the kilogram is that it has been discovered that the mass of this cylinder has been changing over the years (most likely due to reactions with chemicals in the atmosphere). While in most cases a small change of a few micro-grams won't drastically change how our world works, it does not do to have a variable definition of a standard unit of measure.

 

 

As seen in this article, http://eandt.theiet.org/news/2014/sep/kilogram-birthday.cfm, there are currently scientists who are currently working on devising a new definition of the kilogram. This new definition would redefine the kilogram in terms of Max Plank's constant, and simultaneously fixing inconsistencies in both the kilogram and Plank's constant, while also being able to add units such as ohms and volts to the SI units system, rather than just to have them as part of a conventional unit system. Currently on track for 2018, this theoretical redefinition of the kilogram would also make it such that any person can have access to what a true kilogram would be, rather than needing to compare with a cylinder whose mass may or may not be the same as it was last year. 

 

 

I personally thought this was pretty neat, considering all other units of measure have already been well defined and established before my birth, I think it'll be a neat story to tell my future grand kids. I can just imagine being a crotchety old man shouting nonsense about how I remember the world before we had a true kilogram and what a scarry and terrifying world it was.... Though, it does make me sad that nobody will be able to pull off the greatest heist in the history of mankind once this redefinition is solidified. Seriously, what could be more badass that stealing the definition of mass itself?  Someone get on this, write a book or something

I still don't understand what was wrong with 1kg being a 10cm by 10cm cube of dihydrogen monoxide at 4℃.

Don't forget there's also the kilogram sphere of Silicon-28 (if that sphere were the Earth, the highest mountain and deepest valley would be only 14 metres apart, it's that perfectly round), where they can count and write down the number of Si-28 atoms and use that as a check and balance for the redefinition of Planck's Constant for defining the kilogram.

Geek cred right here folks! xD

I can only imagine what might be considered the official measure of weight for an outdated system:   A slightly L shaped scone cooked by the kings hand maid at 2am in an open fire.

As a US citizen, I doubt that would happen, but I can tell you that the pound we use for measuring weight (not the GBP) is actually based off of a definition of what the kilogram is, so we still benefit from this upgrade

Essentially yes. Also here's the video for anyone else reading this who wants to know what the hell we're talking about and doesn't already:

Technically, it already has. The redefinition of US units based of the SI units happened in the mid 1900s: https://www.ngs.noaa.gov/PUBS_LIB/FedRegister/FRdoc59-5442.pdf

 

So, the US is technically using SI as a foundation.

HAH, because 0 degrees is illogical as the point of freezing to you?

Because water boiling at exactly 100 degrees and freezing at exactly 0 degrees is harder to imagine than the random numbers of 212 and 32?
