746 # by the American Antarctic explorer Paul Siple in 1939. As currently used

824 K_J 483597.9 GHz/V # Direct measurement of the volt is difficult. Until
|
|
825 # recently, laboratories kept Weston cadmium cells as
|
|
826 # a reference, but they could drift. In 1987 the
|
|
827 # CGPM officially recommended the use of the
|
|
828 # Josephson effect as a laboratory representation of
|
|
829 # the volt. The Josephson effect occurs when two
|
|
830 # superconductors are separated by a thin insulating
|
|
831 # layer. A "supercurrent" flows across the insulator
|
|
832 # with a frequency that depends on the potential
|
|
833 # applied across the superconductors. This frequency
|
|
834 # can be very accurately measured. The Josephson
|
|
835 # constant K_J, which is equal to 2e/h, relates the
|
|
836 # measured frequency to the potential. The value
|
|
837 # given here is the officially specified value for
|
|
838 # use beginning in 1990. The 2006 recommended value
|
|
839 # of the constant is 483597.891 GHz/V.
|
|
840 R_K 25812.807 ohm # Measurement of the ohm also presents difficulties.
|
|
841 # The old approach involved maintaining resistances
|
|
842 # that were subject to drift. The new standard is
|
|
843 # based on the Hall effect. When a current carrying
|
|
844 # ribbon is placed in a magnetic field, a potential
|
|
845 # difference develops across the ribbon. The ratio
|
|
846 # of the potential difference to the current is
|
|
847 # called the Hall resistance. Klaus von Klitzing
|
|
848 # discovered in 1980 that the Hall resistance varies
|
|
849 # in discrete jumps when the magnetic field is very
|
|
850 # large and the temperature very low. This enables
|
|
851 # accurate realization of the resistance h/e^2 in the
|
|
852 # lab. The value given here is the officially

853 # specified value for use beginning in 1990.

1220 # Photographic Exposure Value

1221 #
|
|
1222 # The Additive Photographic EXposure (APEX) system developed in Germany in
|
|
1223 # the 1960s was an attempt to simplify exposure determination for people
|
|
1224 # who relied on exposure tables rather than exposure meters. Shortly
|
|
1225 # thereafter, nearly all cameras incorporated exposure meters, so the APEX
|
|

|

1277 # Astronmical time measurement is a complicated matter. The length of the true
|
|
1278 # day at a given place can be 21 seconds less than 24 hours or 30 seconds over
|
|
1279 # 24 hours. The two main reasons for this are the varying speed of the earth
|
|
1280 # in its elliptical orbit and the fact that the sun moves on the ecliptic
|
|
1281 # instead of along the celestial equator. To devise a workable system for time
|
|
1282 # measurement, Simon Newcomb (1835-1909) used a fictitious "mean sun".
|
|
1283 # Consider a first fictitious sun traveling along the ecliptic at a constant
|
|
1284 # speed and coinciding with the true sun at perigee and apogee. Then
|
|
1285 # considering a second fictitious sun traveling along the celestial equator at
|
|
1286 # a constant speed and coinciding with the first fictitious sun at the
|
|
1287 # equinoxes. The second fictitious sun is the "mean sun". From this equations
|
|
1288 # can be written out to determine the length of the mean day, and the tropical
|
|
1289 # year. The length of the second was determined based on the tropical year
|
|
1290 # from such a calculation and was officially used from 1960-1967 until atomic
|
|
1291 # clocks replaced astronomical measurements for a standard of time. All of the

2747 # In the USA, a collection of crazy historical paper measures are used. Paper
|

2748 # is measured as a weight of a ream of that particular type of paper. This is

2749 # sometimes called the "substance" or "basis" (as in "substance 20" paper).
|
|
2750 # The standard sheet size or "basis size" varies depending on the type of
|
|
2751 # paper. As a result, 20 pound bond paper and 50 pound text paper are actually
|
|
2752 # about the same weight. The different sheet sizes were historically the most
|
|
2753 # convenient for printing or folding in the different applications. These

2754 # different basis weights are standards maintained by American Society for

3691 # In vacuum science and some other applications, gas flow is measured
|
|
3692 # as the product of volumetric flow and pressure. This is useful
|
|
3693 # because it makes it easy to compare with the flow at standard
|
|
3694 # pressure (one atmosphere). It also directly relates to the number
|
|
3695 # of gas molecules per unit time, and hence to the mass flow if the
|
|
3696 # molecular mass is known.

|
|
3710 #
|
|
3711 # This area is a nightmare with huge charts of wire gauge diameters
|
|
3712 # that usually have no clear origin. There are at least 5 competing wire gauge
|
|
3713 # systems to add to the confusion. The use of wire gauge is related to the
|
|
3714 # manufacturing method: a metal rod is heated and drawn through a hole. The
|
|
3715 # size change can't be too big. To get smaller wires, the process is repeated
|
|
3716 # with a series of smaller holes. Generally larger gauges mean smaller wires.
|
|
3717 # The gauges often have values such as "00" and "000" which are larger sizes
|
|
3718 # than simply "0" gauge. In the tables that appear below, these gauges must be
|
|
3719 # specified as negative numbers (e.g. "00" is -1, "000" is -2, etc).
|
|
3720 # Alternatively, you can use the following units:
|
|
3721 #
|
|
3722
|
|
3723 g00 (-1)
|

|

|
|
3729
|
|
3730 # American Wire Gauge (AWG) or Brown & Sharpe Gauge appears to be the most
|
|
3731 # important gauge. ASTM B-258 specifies that this gauge is based on geometric
|
|
3732 # interpolation between gauge 0000, which is 0.46 inches exactly, and gauge 36
|
|
3733 # which is 0.005 inches exactly. Therefore, the diameter in inches of a wire
|
|
3734 # is given by the formula 1|200 92^((36-g)/39). Note that 92^(1/39) is close
|
|
3735 # to 2^(1/6), so diameter is approximately halved for every 6 gauges. For the
|
|
3736 # repeated zero values, use negative numbers in the formula. The same document
|
|
3737 # also specifies rounding rules which seem to be ignored by makers of tables.
|
|
3738 # Gauges up to 44 are to be specified with up to 4 significant figures, but no
|
|
3739 # closer than 0.0001 inch. Gauges from 44 to 56 are to be rounded to the
|
|
3740 # nearest 0.00001 inch.
|
|
3741 #
|
|
3742 # In addition to being used to measure wire thickness, this gauge is used to
|
|
3743 # measure the thickness of sheets of aluminum, copper, and most metals other
|
|
3744 # than steel, iron and zinc.

3769 # The following is from the Appendix to ASTM B 258
|
|
3770 #
|
|
3771 # For example, in U.S. gage, the standard for sheet metal is based on the
|
|
3772 # weight of the metal, not on the thickness. 16-gage is listed as
|
|
3773 # approximately .0625 inch thick and 40 ounces per square foot (the original
|
|
3774 # standard was based on wrought iron at .2778 pounds per cubic inch; steel
|
|
3775 # has almost entirely superseded wrought iron for sheet use, at .2833 pounds
|
|
3776 # per cubic inch). Smaller numbers refer to greater thickness. There is no
|
|
3777 # formula for converting gage to thickness or weight.
|
|
3778 #
|
|
3779 # It's rather unclear from the passage above whether the plate gauge values are
|
|
3780 # therefore wrong if steel is being used. Reference [15] states that steel is
|
|
3781 # in fact measured using this gauge (under the name Manufacturers' Standard
|
|
3782 # Gauge) with a density of 501.84 lb/ft3 = 0.2904 lb/in3 used for steel.
|
|
3783 # But this doesn't seem to be the correct density of steel (.2833 lb/in3 is
|
|
3784 # closer).
|
|
3785 #
|
|
3786 # This gauge was established in 1893 for purposes of taxation.

3842 # fractions of particles that are passed or retained by different mesh
|
|
3843 # sizes. As a result, it is not possible to make precise comparisons
|

3844 # of different grit standards. The tables below allow the
|
|
3845 # determination of rough equivlants by using median particle size.
|
|
3846 #
|
|
3847 # Standards in the USA are determined by the Unified Abrasives
|
|
3848 # Manufacturers' Association (UAMA), which resulted from the merger of
|
|
3849 # several previous organizations. One of the old organizations was
|
|
3850 # CAMI (Coated Abrasives Manufacturers' Institute).
|
|
3851 #
|
|
3852 # UAMA has a web page with plots showing abrasve particle ranges for
|
|
3853 # various different grits and comparisons between standards.

|
|
3857 # Abrasives are grouped into "bonded" abrasives for use with grinding
|
|
3858 # wheels and "coated" abrasives for sandpapers and abrasive films.
|
|
3859 # The industry uses different grit standards for these two
|
|
3860 # categories.
|
|
3861 #
|
|
3862 # Another division is between "macrogrits", grits below 240 and
|
|
3863 # "microgrits", which are above 240. Standards differ, as do methods
|
|
3864 # for determining particle size. In the USA, ANSI B74.12 is the
|
|
3865 # standard governing macrogrits. ANSI B74.10 covers bonded microgrit
|
|
3866 # abrasives, and ANSI B74.18 covers coated microgrit abrasives. It
|
|
3867 # appears that the coated standard is identical to the bonded standard
|
|
3868 # for grits up through 600 but then diverges significantly.
|
|
3869 #
|
|
3870 # European grit sizes are determined by the Federation of European
|
|
3871 # Producers of Abrasives. http://www.fepa-abrasives.org
|
|
3872 #
|
|
3873 # They give two standards, the "F" grit for bonded abrasives and the

3874 # "P" grit for coated abrasives. This data is taken directly from

3875 # their web page.
|

3876
|

3877 # FEPA P grit for coated abrasives is commonly seen on sandpaper in
|
|
3878 # the USA where the paper will be marked P600, for example. FEPA P
|
|
3879 # grits are said to be more tightly constrained than comparable ANSI

4147 # circulation. According to [15], the interior diameter of size n ring in

4148 # inches is 0.32 n + 0.458 for n ranging from 3 to 13.5 by steps of 0.5. The

4149 # size 2 ring is inconsistently 0.538in and no 2.5 size is listed.

4152 # diameter and list no special case for size 2. (Or alternatively they are

4153 # 1.43 + .102 n and 1.4216+.1018 n for measuring circumference in inches.) One
|

4446 # The traditional system of weights and measures is called shakkanhou from the
|

4447 # shaku and the ken. Japan accepted SI units in 1891 and legalized conversions
|
|
4448 # to the traditional system. In 1909 the inch-pound system was also legalized,
|
|
4449 # so Japan had three legally approved systems. A change to the metric system
|
|
4450 # started in 1921 but there was a lot of resistance. The Measurement Law of
|
|
4451 # October 1999 prohibits sales in anything but SI units. However, the old
|
|
4452 # units still live on in construction and as the basis for paper sizes of books

4453 # and tools used for handicrafts.

4454 #
