For each physical quantity, a number of different units some only of historical interest are shown and expressed in terms of the corresponding SI unit. Engineering judgment may include such factors as:.
A velocity consists of a speed combined with a direction; the speed part of the velocity takes units of speed. Available from Astrophysics Data System. The general relationship between absorbed dose and equivalent dose can be represented as. By contrast, a hard conversion or an adaptive conversion may not be exactly equivalent. American dictionary of printing and bookmaking.
Conversion between weight force and mass. There are many conversion tools. Proceedings of the Vatican Conference to Commemorate its th Anniversary.
For the conversion of units on Wikipediasee Template: The inductance of a closed circuit that produces one volt of electromotive force when the current in the circuit varies at a uniform rate of one ampere per second.
Retrieved 29 May US Government Printing Office, pp.
Because of the identity property of multiplication, the value of a quantity will not change as long as it is multiplied by one. The process of conversion depends on the specific situation and the intended purpose.
How to Change Units. It does not involve changing the physical configuration of the item being measured.
Conversion of units
CFM [ citation needed ]. They are found in the function libraries of applications such as spreadsheets databases, in calculators, and in macro packages and plugins for many other applications such as the mathematical, scientific and technical applications.
GPH [ citation needed ]. National Institute of Standards and Technology. The unity bracket method of unit conversion  consists of a fraction in which the denominator is equal to the numerator, but they are in different units.
Metric units of length review (mm, cm, m, & km) (article) | Khan Academy
Modern standards such as ISO prefer the shannon to the bit as a unit for a quantity of information entropy, whereas the discrete storage space of digital devices is measured in bits.

Refinement of values for the yard and the pound. The practice of typography: Archived from the original on This article gives lists of conversion factors for each of a number of physical quantities, which are listed in the index.
So as long as the numerator and denominator of the fraction are equivalent, they will not affect the value of the measured quantity. Varies and is poorly reproducible. The multiples of a bit listed above are usually used with this meaning.
