Further minor variations exist where European or Japanese manufacturers round a U measurement up or down to some closer convenient metric equivalent ; for example the common 5U modules are exactly 8. 75 " ( 222. 25mm ), but non-American manufacturers may prefer 220mm or 230mm.

Current accounting rules under International Accounting Standards and U. S. GAAP allow managers some choice in determining the methods of measurement and criteria for recognition of various financial reporting elements.

There is no standard measurement rating in the U. S., so a 20 ° bag from one company may not provide the same warmth as a 20 ° from another company.

In 1968, Congress authorized the U. S. Metric Study, a three-year study of systems of measurement in the U. S., with emphasis on the feasibility of metrication.

The final report of the study concluded that the U. S. would eventually join the rest of the world in the use of the metric system of measurement.

The U. S. military, reflecting its need to ensure interoperability with its NATO allies, uses metric measurements for almost all weapons calibers, even when the caliber in question originated as or was derived from a different measurement ( e. g. 7. 62 mm rather than. 308, or 5. 56 mm instead of. 223 ).

The U. S. territory of Puerto Rico generally uses American-style ( MUTCD ) signs with metric measurement on highways, displaying kilometer posts and distances in km, yet speed limit signs are in miles per hour.

Any measurement that combines customary units with electrical units is necessarily hybrid, since there are no U. S. customary electrical units.

The overall precision of m depends on the precisions of the measurements of U, I, v and g. Since there are already methods of measuring v and g to very high precision, the uncertainty of the mass measurement is dominated by the measurements for U times I, which is the value measured by the watt balance.

Such an interferometer provides a means of absolute temperature measurement, and may be used as an alternative to the gas thermometer.

A study of the hydrogen line profiles indicates that a measurement of these profiles can be used to calculate a temperature for the arc plasma that is reliable to about Af percent.

These curves were derived by an analysis of extensive skywave measurement data.

He became particularly interested in graduating and precision measurement during the 1840's, and his thinking along these lines developed considerably during this period.

Throughout their careers, both Mr. Brown and Mr. Sharpe were interested in the problem of setting up standards of measurement for the mechanical trades.

A tire must be inflated to its normal hot operating pressure and the car must be loaded to its operating weight when this measurement is made.

The measurement must be in inches.

Any fraction of an inch involved in the measurement must be converted to a decimal equivalent to simplify the mathematics.

For top and bottom pieces, use short end of mold as measurement guide.

This pressure measurement may be made at the same time that the ultrasonic dimensioning measurement is made.

Two pyrometers shown in figure 1 and 2 ( Pyrometer Instrument Co. Model 95 ) served for simultaneous measurement of the anode surface temperature and the temperature distribution along the anode holder.

The face of one block contained a hole 1/16'' '' in diameter which led to a manometer for the measurement of the normal pressure.

They also give information which will aid in the design of a more satisfactory instrument for the measurement of the normal pressures.

The elasticity is a parameter of fluids which is not subject to simple measurement at present, and it is a parameter which is probably varying in an unknown manner with many commercial materials.

One measurement at 40 Mc/sec was obtained with the Varian model Af unit.

A single measurement of the spin - spin relaxation time Af was obtained at 10 Mc/sec by pulse methods.

This measurement was obtained by W. Blumberg of the University of California, Berkeley, by observing the breadth of the free induction decay signal.

The temperature was maintained to within about Af for the period of time required to make the measurement ( usually about one hour ).

The most convincing recent measurement of an anaconda was made in eastern Colombia by Roberto Lamon, a petroleum geologist of the Richmond Oil Company, and reported in 1944 by Emmett R. Dunn.

However, as a field measurement, it is open to question.

But our present interest lies in the measurement of costs of service, and only indirectly in rates that may or may not be designed to cover these costs.

This question might be settled by comparing the measurement of the actual circumference with the dimensions noted, presumably in Brumidi's hand, above the various sections of his long preparatory drawing, which has been kept.

Therefore, the on-the-scene commander must have detailed operating instructions based on measurement of conditions, in the area, at the time of encounter.

A number of adjustment features are included in the Hesiometer to facilitate measurement and permit ready removal of coatings deposited on such substrates as iron and other metals, glass, wood, and plastic surfaces.
