the real unit behind the sievert is the J/s, which is equivalent to Watts

No, it's a measure of energy absorbed - Joules per kilogram

The main advantage to me of the metric system has been the prefixes which allow for having only one unit for each type of measurement, and then simply using powers of 10 to deal with very large or small numbers. This doesn't apply in temperatures, no one uses kilodegrees.

I was all set to jump on you with "Centigrade". Then, I decided to look it up. I found some interesting info here:
Centigrade

Or, more likely IMHO, because the cloth it's made of is called duck cloth.

However, the total volume of an Imperial gallon and a US statute gallon is one gallon. It is just that the number of smaller or larger ounces is different.If you buy ten gallons of fuel in the UK, you have ten gallons of fuel by US volume, as well.

While you're correcting people, make sure you get the unit right! 9 million barrels is 378 million gallons. 1 barrel = 42 gallons

"Robert Birge (Syracuse University) who studies the storage of data in proteins, estimated in 1996 that the memory capacity of the brain was between one and ten terabytes, with a most likely value of 3 terabytes. Such estimates are generally based on counting neurons and assuming each neuron holds 1 bit. Bear in mind that the brain has better algorithms for compressing certain types of information than computers do."

"The human brain contains about 50 billion to 200 billion neurons (nobody knows how many for sure), each of which interfaces with 1,000 to 100,000 other neurons through 100 trillion (10 14) to 10 quadrillion (10 16) synaptic junctions. Each synapse possesses a variable firing threshold which is reduced as the neuron is repeatedly activated. If we assume that the firing threshold at each synapse can assume 256 distinguishable levels, and if we suppose that there are 20,000 shared synapses per neuron (10,000 per neuron), then the total information storage capacity of the synapses in the cortex would be of the order of 500 to 1,000 terabytes. (Of course, if the brain's storage of information takes place at a molecular level, then I would be afraid to hazard a guess regarding how many bytes can be stored in the brain. One estimate has placed it at about 3.6 X 10 19 bytes.)"

Okay, quick Google search to verify my education, and you get this:
http://scienceworld.wolfram.com/physics/Pound.html

which agrees with me, and this:

which agrees with you. You also get some discussion, and some confusion. I think the dicussion supports my understanding, but I'm biased. I don't know where to look for a clear answer (OED isn't written by physicists).

How about this: The official unit of mass in the Imperial system is the slug. The slug is defined by: 1 lb = 1 slug * 1 ft/sec^2 . The pound was already standard, and a force, so they derived the official mass from it, much as the Newton is derived from the kilogram. If the pound was a mass that equation would not give slug as a mass, and, more to the point, there would be a derived force unit, instead of a derived mass unit. Convinced?

In reality, since there is confusion, we just always use lbm and lbf where it isn't blatantly obvious. I actually do prefer SI units (just MKS and some electrical stuff, not Joules, Newtons, etc), but since I work in American industry, I have become rather familiar with the "old ways".

with your funny measurements probably measure temperatures in ounces, feet or hands or something. :)

or maybe the body temperaure of your wife?

Apparently you are wrong.
The kilogram originated in the reforms of the French Revolution. Conceptually, it was to be the mass of a cubic decimeter of water at water's maximum density. It was originally called a grave, but the name was changed to kilogram in 1795.
