Units multipliers

For the moment, let us define a/47teQ as Oy, where the subscript V reminds us that the polarizability is being expressed in volume units. Multiplying the numerator and denominator of Eq. (10.33) by (4 ) gives... 

FIG. 18-93 Approximate installed cost of single-compartment thickeners (1995 dollars). To convert to ft and fr units, multiply diameter in meters by 3.28 and divide cost by 10.76. 

To convert calories per mole to British Th( mial Units, multiply hy 1.8. 

Note To convert conventional units (mg/dL) to SI calcium units multiply by a factor of 0.25. 

The metric system, which is federally mandated and appears in the official listing of drugs in the United States Pharmacopoeia (USP), is a logically organized system of measurement. It was first developed by the French. The basic units multiplied or divided by 10 comprise the metric system. Therefore, a knowledge of decimals, reviewed in Chapter 1, is useful for this system. 

To convert milligram (large unit) to microgram (small unit), multiply by 1000 or move the decimal point three places to the right. 

Level of toxicity Toxic unit Multiplying coefficient... 

Parameter Lab unit Multiply by Pert, value (metric)... 

Specific speed derived using SI units multiplied by a factor of 51,64 is equal to specific speed in US Customary units. 

You may encounter questions that ask you to convert between units of measurement in length, weight, or time. To convert from a smaller unit (such as inches) to a larger unit (such as feet), divide the smaller unit by the number of those units necessary to equal the larger unit. To convert from a larger unit to a smaller unit, multiply the larger unit by the conversion number. 

Figure 1. Modulus of the matrix elements M for the transition 11 25 1/s) 22Si/a in atomic units multiplied by a factor Z4 as a function of nuclear charge Z. The solid line represents the nonrelativistic dipole (NRD), the dashed line the nonrelativistic retarded (NRR), the dot-dashed line the relativistic dipole (RD), and the dotted line the relativistic retarded (RR) result.

These values of A are in molecular units, and cannot be compared directly with a typical value of Z. This is because partition functions are molecular quantities and the contributions to K kT/h)Q /QxQyz are in molecular units. Multiplying by... 

Given a quantity in these units Multiply by To convert quantity to these units... 

To convert to other units, multiply esu or cgs field strength by 30,000 to get mks field strength i.e.,... 

To convert from Unit To Unit Multiply the latter by Reference... 

To convert a quantity expressed in terms of one unit to its equivalent in terms of another unit, multiply the given quantity by the conversion factor (new unit/old unit). For example, to convert 36 mg to its equivalent in grams, write... 

Quantity SI unit/symbol Old unit/symbol Multiply number in old unit by this factor for equivalent in SI unit Multiply number in SI unit by this factor for equivalent in old unit ... 

The reported uncertainty is an expanded uncertainty based on a standard uncertainty of 0.1 units multiplied by a coverage factor of two, which provides a confidence level of approximately 95%. 

Activities can be expressed in concentration units multiplied by an activity coefficient. For a gas, aj = = yjPj numerically. For a solute, Oj = = [J] numerically. 

Physical quantity Customary unit SI unit To convert from customary unit to SI units multiply by... 

It can be shown that 1 coulomb is equal to 1 esu unit multiplied by ten times the velocity of light in metres per second ... 

To convert a pressure value from a unit in the left-hand column to a new unit, multiply the value by the factor appearing in the column for the new unit. For example ...
