The book-to-bill ratio, also known as the BB ratio or BO/BI ratio, [1] is the ratio of orders received to the amount billed for a specific period, usually one month or one quarter. It is widely used in the technology sector and especially in the semiconductor industry, where the semiconductor manufacturing equipment (SME) book-to-bill ratio is ...
Though the BBP formula can directly calculate the value of any given digit of π with less computational effort than formulas that must calculate all intervening digits, BBP remains linearithmic (()), whereby successively larger values of n require increasingly more time to calculate; that is, the "further out" a digit is, the longer it ...
The following formulas can be used to calculate the volumes of solute (V solute) and solvent (V solvent) to be used: [1] = = where V total is the desired total volume, and F is the desired dilution factor number (the number in the position of F if expressed as "1/F dilution factor" or "xF dilution"). However, some solutions and mixtures take up ...
Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...
Your current ratio tells you how prepared you are to manage your debts during a financial emergency. You can calculate your current ratio by following these steps: Add up your current assets ...
In this mode the template converts two values conjoined with the given word. The first value is determined by 1 and the second value is determined by 3 . In dual conversion mode the number of significant figures in the output can be given by 4 .
A number of different units (some only of historical interest) are shown and expressed in terms of the corresponding SI unit. Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article.
In numerical analysis, order of accuracy quantifies the rate of convergence of a numerical approximation of a differential equation to the exact solution. Consider u {\displaystyle u} , the exact solution to a differential equation in an appropriate normed space ( V , | | | | ) {\displaystyle (V,||\ ||)} .
