Measure Formats

This is a collection of existing measure formats.

Normalized Scientific Notation

Normalized Scientific Notation for measured values has been used for decades worldwide.

Also, observational errors are inherently defined in any measuring process.

UNECE

UNECE, the United Nations Economic Commission for Europe has standardized the measurement unit codes for use in Trade.

ACORD

ACORD, a leading insurance standardization organization uses the following semantics for expressing measures:

• Measurement
  • NumUnits (Required) Decimal
  • UnitMeasurementCd (Optional) the value must be one of the ones defined by UNECE.

Systeme International

The internation system of measures consists of base and derived units of measure.

For instance, meter (m) is the elementary unit of length, second (s) the elementary unit of time, and speed or velocity is derived and expressed in meter per second (m/s).

SI Base Units

Name	Symbol	Quantity
metre	m	Length
kilogram	kg	Mass
second	s	Time
ampere	A	Electrical current
kelvin	K	Thermodynamic temperature
mole	mol	Amount of substance
candela	cd	Luminous intensity

SI Derived Units

area square meter m2 volume cubic meter m3 speed, velocity meter per second m/s acceleration meter per second squared m/s2 wave number reciprocal meter m-1 mass density kilogram per cubic meter kg/m3 specific volume cubic meter per kilogram m3/kg current density ampere per square meter A/m2 magnetic field strength ampere per meter A/m amount-of-substance concentration mole per cubic meter mol/m3 luminance candela per square meter cd/m2 mass fraction kilogram per kilogram, which may be represented by the number 1 kg/kg = 1

The Unified Code for Units of Measure

The Unified Code for Units of Measure

UBL

"UBL is designed to provide a universally understood and recognized commercial syntax for legally binding business documents and to operate within a standard business framework such as ISO 15000 (ebXML) to provide a complete, standards-based infrastructure that can extend the benefits of existing EDI systems to businesses of all sizes."

UBL uses the following semantics for prices:

• In the context of an Order. a LineItem can have a Quantity which is qualified with a unitCode.
• In the context of the price of a product: a Price has a PriceAmount qualified with a currencyID, and a BaseQuantity (usually 1) qualified with a unitCode.

The value of unitCode are those defined by UNECE.
