  Conversion of Units of Measurement
Conversion of units must be done explicitly by the programmer; this can be both burdensome and error-prone, since the conversion factors used by the programmer might be entered incorrectly or might have limited accuracy.
Unit conversion may also be required in preparing data for transmission to a remote site over a network, or for use in a remote procedure call.
Conversion of units may generate extra multiplication operations; however, if the compiler performs constant folding [aho], these operations and their conversion factors can often be combined with other constants.

  Metric Conversion
Regulations on the use of metric units for WEIGHTS AND MEASURES in retail trade were established and enforced by the government for the protection of consumers and retailers against unfair practices and confusion in comparing products.
Opponents of metric conversion pointed to the costs at a time of inflation and economic weakness, the danger of being out of step with the US and the invasion of a foreign language of measurements upon a Canadian heritage bound to imperial measurements.
SI is simple because of its decimal nature and the absence of a multiplicity of units with conversion factors.

  Units conversion by factor-label - Wikipedia, the free encyclopedia
Converting from one dimensional unit to another is often somewhat complex and being able to perform such conversions is an important skill to acquire.
The factor-label method is the sequential application of conversion factors expressed as fractions and arranged so that any dimensional unit appearing in both the numerator and denominator of any of the fractions can be cancelled out until only the desired set of dimensional units is obtained.
Having the same units on both sides of an equation does not guarantee that the equation is correct, but having different units on the two sides of an equation does guarantee that the equation is wrong.

 Conversion of Units
The conversion of numbers from one system of units to another often puzzles students, but if it is treated as just another problem in arithmetic using arithmetic's rules the problems disappear.
Notice that the quantities 2.54 cm/in and 10 mm/cm were used but, because the units had to be squared, then the numbers that accompanied them had also to be squared.
Notice that the only tricky part here is the time conversion 3600 s/hr which is the wrong way up for our conversion but of course it is equally true that there are (1/3600) hr/s.

 General Tables of Units of Measurement   (Site not responding. Last check: )
TABLES OF METRIC UNITS OF In the metric system of measurement, designations of multiples and sub-divisions of any unit may be arrived at by combining with the name of the unit the prefixes deka, hecto, and kilo meaning, respectively, 10, 100, and 1000, and deci, centi, and milli, meaning, respectively, one-tenth, one-hundredth, and one-thousandth.

 Unit Converter - Adding New Units
The two primary conversion units for Length are Feet and Meters, and all units in the Length measurement class have a conversion factor to either Feet or Meters.
Second, it gives the user the ability to add a measurement unit to a measurement class, enter a single conversion factor for that unit, and then be able to convert from that unit to all other units in that class.
For example, if a user wanted a unit called a “half-meter”, then they could enter in a conversion factor for Half-meter to convert it to an appropriate primary conversion unit (Meter), and then they would be able to convert Half-meters to and from all 77 other length units.

 Online Conversion - The Imperial Units
In the United States and in a few Caribbean countries, the U.S. customary units, which are similar to Imperial units based upon older English units and in part share definitions, are still in common use.
The use of SI units is increasingly mandated by law for the retail sale of food and other commodities, but many British people still use Imperial units in colloquial discussion of distance (miles and yards), speed (miles per hour), weight (stones and pounds), liquid (pints and gallons) and height (feet and inches).
Traditional units persist in ordinary conversation and may be experiencing a resurgence due to the reduction in trade barriers with the United States.

 NICMOS Units Conversion Help
The NICMOS Units Conversion Program is a tool for converting fluxes of astronomical sources from units which are widely used in Astronomy (e.g., magnitude, ergs/sec/cm^2/A, etc.) into Jansky (Jy), and vice versa.
The Jy, or, for the case of extended sources, Jy/arcsec^2, is the flux unit adopted in the NICMOS Handbook and used by the NICMOS Exposure Time Calculator.
Unit conversion between magnitude and fluxes, and vice versa, requires information on the magnitude zero-point value and on the bandpass central wavelength.
