I was reading about oil wells this morning (rrs mode - really random surfing) and found that the length of the drillstring is measured in mKB..
Hmmm. . what is a mKB?
A bit of searching turned up the answer - meters below the Kelly bushing. The Kelly bushing is the device at the top of the drillstring that spins the entire string. If you want the vertical depth you are talking about mSS (meters subsurface).
A great site for finding such things as well as browing is How Many?
recommended!
I think the US was the first country to have a decimal currency - probably Jefferson's doing as he was interested in decimal everything (other than time, but perhaps he did think about the beat).
While decimals are very convenient for computation I doubt that most people could measure out a tenth of something (power, liquid) as easily as they could measure an eighth (half * half * half).
