I had a good one just now:

How the fucking fuck could I not know that? Public school, you have failed me.

So a kilogram is a liter of water, which is 1,000 cubic centimeters, which is also, apparently, 1,000 grams and could be used to define a 'fluid gram,' (as in, 'fluid ounce'). WHY DO WE NOT USE THE METRIC SYSTEM YET?!

edit: to clarify, I knew 'kilogram = 2.2lbs,' which I don't think school taught me, either. But I could not recall off the top of my head how to use a known volume of water to measure weight.
 
I don't get the outrage, US don't use metric system so you don't know. If you knew the metric system then you would know the logic behind it and its underlying simplicity. Big deal...

It's like saying how the fuck did I know know what "cào nǐ mā" means, after all it has the work "ma"... well its because you were never taught Chinese...
 
I didn't know that but i don't feel like an idiot because metric is stupid.


/grabs popcorn.

notsureifserious.

I knew the volume relationship between liters/meters (more commonly, of course, milliliters/cubic centimeters) but not their correlation to the mass of water.

Funny, I remember learning that in public school. :\

1ml of water is also 1cm^3 (cubed) is also 1g. This only applies to water in all units due to the density being almost perfectly 1g/ml - it is only exactly that measurement at 4ºC, which is something I only learned just now when confirming the density. I thought it was off, and at all other temperatures it is less than 1g/ml. Water is a strange substance.
 
I learned that in high school.

My stupid googling... hmm... how to portmanteau that. Stoogling, maybe?

Anyway, usually I'm using it to check spelling.

Because Americans are pigheaded idiots. I so enjoy doing math before doing the math I'm really interested in. It makes work last longer, and I'm always looking for ways to make work last longer...

I can answer this one! It's because water expands when it freezes (making it even more unusual) due to hydrogen bonding

So, you only knew half the relationship?

1 CC simply represents absolute volume, IIRC. It does equal liquid volume (1mL), but not mass, as that depends on the properties of what fills that volume.

1 CC of water also is 1g.

I guess I was incorrect when I assumed the entire basis of the metric system was based on water and it's relationship with in volume and mass.

This is what I found to be interesting:
http://water.usgs.gov/edu/density.html

At no temperature, colder or warmer, is water more dense than at 39.2ºF/4ºC. It is less dense at 40ºF/4.4ºC, and less dense at 32ºF/0º (and, I am assuming, at 38ºF). I understand it is less dense when frozen, which is, true, unusual for liquids, however, that it is less dense when warmer is also odd.

If you look above, I did address 1mL = 1 CC = 1g when applied to water.

However, I think you are actually correct. I had not known--though it makes sense--that the gram was in fact originally defined as 1mL of water at 4ºC. (http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch1/)

Edit:
now the gram is defined as 1/1000th of the kilogram, which is based on a prototype mass unit preserved by the SI folks. I think they did that to prevent atmospheric differences, as that kilogram should have the same mass at any pressure, even in space, whereas 1mL, I assume, has different volume and mass relationships based on atmospheric pressure.

Huh?

How would someone knowing that cc stands for "cubic centimeter" figure out that one cc of water weighs one gram? That makes no sense.

Apparently, the teaching of simple logic these days is equally bad.

Why would you learn about a CC of water without learning about the rest of the accompanying relationships? Perhaps, I went to a better school than most of you (which is laughable, if you ask me), but I learned that one CC of water is equal to 1ml of volume and 1g of mass.

You assume. A cc is a common unit of volume. You can know that a cc and a ml are equivalent without knowing anything about the weight of a cc of water.

How is that odd. The only odd thing is that is becomes less dense when solid. Becoming less dense when warmer is what pretty much every liquid does.

You are correct, my bad. I worded that wrong.

Water's peak density is at 4ºC. It is not frozen at 3ºC, yet it less dense. From melting point to 4ºC, water rises in density. It then proceeds to become less dense at higher temperatures. So after 4ºC, it follows the trend of most liquids, but it doesn't follow it immediately after the melting point. I don't know if THAT is also a normal trend for other liquids. I think that may be unique, and is probably a direct result of the fact that it is less dense as a solid.
