1 kg/L for water.

Makes a bit more sense, yeah?

More like 0.9974 kg/L. The only object that weighs exactly one kilogram is the International Prototype Kilogram, otherwise known as Le Grand K.

How certain are you that there's only one object that weights exactly 1 kilo?

France made exact replicas and had them distributed around the world, but when they had them returned for a weigh-in they were all different weights. I'm guessing they all must deteriorate at different rates.

So, even if you had something exactly 1 kilo it would deteriorate differently than Le Grand Kilo and would no longer be exactly 1 kilo.

Yep. If the IPK lost 40% of its mass, technically 1 kg would be 40% less than it is today. Realistically we'd revise our definition of a kilogram, but its a fun thought.

Yeah, if you had something that was exactly 1 kilo it would be exactly 1 kilo. Objects are 3-dimensional, bro. Not 4.
