Wherefrom the humans in the eve-galaxy know, how many weighs a kilogram ... or how long is a meters/metre ...
I know only the story for the time ...

Everything's in Meters, Kilograms etc. for the sake of convenience. The peoples of New Eden probably do use different units of measurement, but it'd be a pain in the ass to "invent" new measurements just for the sake of flavor and then make everyone learn them. So for simplicity's sake the client just "translates" the units into something real life people understand.

Want a cool story like this story about the time ...

We can determine second: It is currently defined as 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 caesium-133 atom.
When we know how long second is we can determine meter which is the length of the path traveled by light in vacuum during a time interval of 1/299,792,458 of a second.
Now we know how long meter is, now we can determine how much _mass_ is one kilogram (not weight). Which is one cubic decimeter (1 litre) of water in 0 celsius temperature. I think so.
mmkay..?

I bet this wasn't the first way seconds were calculated. 
It's most prolly a coincidence that it is, considering the vast possibilities there are with atoms and isotopes.

Yes, but thats how _exact_ second is determined in modern world.

Lazy caesium-133, bad atom. Promise not to lose a few seconds every thousand years and I promise to give you some flourine

I agree on the "used for convenience" definition.
Second was defined originally by the rotation of the Earth, but since it is not constant, it was so redefined that it isn't tied on this planet, and is constant.
Kilogram is actually defined as the mass of the kilogram prototype kept in Paris, France. It is also roughly the same as the mass of one cubic decimeter of water at 4 degrees Celsius (or scientifically said, 280.15 Kelvins). Celsius scale is problematic in scientific use, since even when it's zero point is relatively close to the triple point of water, the 100 degrees point is only the boiling point of water in the pressure of 1 atm (average pressure on Earth's surface on sea level). That said, Kelvin likely has some nice scientific definition as well, so technically the definition as a certain volume (or even certain moles) would apply.

It's at standard temperature and pressure rather than at freezing point.

Zero degrees Celsius is defined as the freezing point of pure water at one atmosphere of pressure.
One hundred degrees Celsius is defined as the boiling point of pure water at one atmosphere of pressure.
Zero Kelvin is defined as absolute zero. This is essentially the temperature of solid crystalline hydrogen with no thermal (ie vibrational) energy. This temperature is around -273ŚC
Each point on the Kelvin scale corresponds to one degree Celsius. The freezing point of water is at approximately 273K, and the boiling point at around 373K.
Whilst it's true that the triple point of water is close to zero degrees Celsius, it's also a long way from atomspheric pressure (0.006atm)

The races in eve are descendants of humans, and for example the current in game calender and clock is based on what they know of old earth calender and clock. So obviously standard basic every-day things like this would have been preserved and kept. While the use of the earth calender and clock may have been temporary discarded (prior to everyone deciding to use it again like the article somewhere explains) due to the trouble of trying to use it on a different planet, standard units of measurement would probably have been kept alive and used for this entire time, because why not?
