"This implementation has now enabled scientists and researchers to base the SI units
entirely on fundamental properties of nature, which will ensure their ongoing refinement and improvement for years to come," according to an official statement released by the government.
All CVs calculated in DCCT units were much lower compared with CVs calculated in SI units
(Table 1) owing to the lower specificity of the NGSP PRMP.
--magnetic constant [[mu].sup.0], which in SI units
is 4[pi] x [10.sup.-7] Henry/metre, is replaced by a new magnetic constant [[mu].sub.o] = 1/[[epsilon].sub.0][c.sup.2] = 0.0344 [[N.sup.-1]].
Each face of the cube has information for one concept associated with SI units
. Kinesthetic and visual learners can use the Cube to help imagine the magnitude of various SI units
: each edge has a length of 0.010 m; the cube has a volume of 1 litre or 1000 mL or 10'3 m3; if filled with water the cube would have mass 1 kg.

Note that ppm and ppb are not SI units
. We also use ppm and ppb when we use solution concentrations in soil science.
One such book, available from AACC (www.AACC.org), is SI Units

The conversion of several domestic FeSi furnaces to Si metal production has shifted some U.S.-producing plants into greater exports of Si units
. The consequence is that the U.S.
30, 1996 - the deadline for submitting federal-aid designs in SI units
If I have to pick the one item that annoyed me, it was his section on SI units
in Chapter 4.
Aiming for two markets the editors decided to use American spelling in American chapters and vice versa, and to compensate for this by including the alternative spelling in parentheses (similarly for SI units
Even when other SI units
are used in the article, I'm always that the traditional shorthand from a first draft might have carried through intact; a difference of [10.sup.3] is sometimes not enough to make the intended meaning obvious, even to an informed reader.
