Raw

v2.2.2 (November 3nd, 2023)

  • Added ronna (R) and quetta (Q) si prefixes.
  • Added IEC prefixed units support for Storage
  • Added Storage units

v2.2.1 (November 2nd, 2023)

  • Drop support of php < 7.2

v2.2.0 (February 17th, 2021)

  • Added support for php 8.0
  • Added option power factor for Si factor, ie for square (2) and cubic (3)
  • Added new Physical Quantity volume flow with commonly used units
  • Added lowercase aliases for temperature units
  • Added Si prefixes for area unit square meter (m^2)
  • Added Si prefixes for volume units cubic meter (m^3) and litres
  • Added Si prefixes for velocity units m/s, m/min and m/h
  • Added Si prefixes for acceleration unit m/s^2
  • Additional units for energy: electronvolt, calorie
  • Additional units for length: light year, parsec
  • Additional units for mass: Hundredweight, US short Ton, US long Ton, Asian picul
  • Additional units for pressure: Torr, Technical atmosphere, Kilo and Mega pound per Square Inch
  • Additional units for velocity: Mach, meters/min, feet per minute, miles per second
  • Additional unit for power: dBm
  • Fixed native unit for mass as gram

v2.1.0 (July 24th, 2016)

  • Added getUnitDefinitions() method to PhysicalQuantity classes, to get a raw list of UnitofMeasure objects defined on that quantity
  • Added UPPERCASE templating support for autogenerated metric units to support names like MEGA_METERS, for example.
  • New Quantity physical quantity, with mole as the standard unit, to represent the Amount of Substance SI base quantity.
  • New SolidAngle physical quantity, with steradian as the standard unit, to represent the solid angle quantity
  • Additional aliases for Area units
  • Additional units for time: decade, century, and millenium
  • Additional units for volume: teaspoon, tablespoon, gallon, quart, fluid ounce, and pint

v2.0.1 (December 12th, 2015)

  • Migrated package from triplepoint/php-units-of-measure to php-units-of-measure/php-units-of-measure.
  • New physical quantity: Energy
  • New units of measure:
    • Area: are and decare
    • Length: nautical mile, mil, AU
    • Mass: stone, also slightly changed definitions of lb and oz
    • Time: yr, and jyr
    • Velocity: km/h, ft/s, mph, knot
  • Automated CI testing now includes HHVM and PHP 7
  • Removed the heavy vagrant git submodule, it was a silly thing.
  • Expanded the Readme for better contribution and installation instructions.

v2.0.0 (March 14th, 2015)

  • Registered units of measure are now properties of PhysicalQuantity classes, and not individual instances of those classes. As such, registering a new unit with a given PhysicalQuantity will make that unit immediately available to all inntances of that class.
    • PhysicalQuantity classes no longer define their units in their constructor, and instead have a new initialize() static method
    • The previously-existing registerUnitOfMeasure() method on physical quantity objects has been replaced with a new static addUnit() method
    • The HasSoUnitsTrait method addMissingSIPrefixedUnits is now static
  • Added the toNativeUnit() method, to return values in their native unit of measure
  • Added the isEquivalentQuantity() method, to support future situations where it's not obvious whether two physical quantities represent the same quantity type
  • getSupportedUnits() is no longer available on physical quantities
  • The PhysicalQuantity parent class is now named AbstractPhysicalQuantity
  • Add a new DemonstrationTests test file, to demonstrate and test typical use cases
  • All library exceptions extend from AbstractPhysicalQuantityException, making catching easier
  • Added an interface for PhysicalQuantities, to support future work where not all physical quantity classes necessarily have the same parent

v1.3.3 (March 15th, 2015)

  • Loosened Composer requirement on PHP version to >=5.3.0 (was previously 5.3.5).

v1.3.1 (August 23rd, 2014)

  • Added information in the README about the new SI prefix units generation

v1.3.0 (August 23rd, 2014)

  • Add support for automatically generating metric-prefixed units from a single base unit
  • Throw an exception on registering units of measure with names or aliases that collide with existing units on that quantity
  • Disallow values that aren't numerical and unit names that aren't strings (ie, type checking)
  • Add new method getSupportedUnits() to Physical Quantities
  • Add new method getAliases() to Units of Measure
  • Add arcminute and arcsecond as angle units
  • Add all SI prefix units to meters, kilograms, seconds, amps, kelvin, candela, pascal, bar, radians, degrees, and arcseconds

v1.2.0 (August 16th, 2014)

  • Drop support for PHP 5.3
  • Moved to PSR-4 namespace convention
  • Drop support for an array of names passed in the constructor as a way to specify aliases for UnitOfMeasure objects; addAlias() now required.
  • Add UnitOfMeasure::nativeUnitFactory() and UnitOfMeasure::linearUnitFactory() convenience factory methods
  • Add optional spelling for 'metres' and 'litres'
  • Add Vagrant-based testing virtual machine, for convenience

v1.1.2 (February 9th, 2014)

  • New units of measure on Area: hectares, international acres
  • New units of measure on Temperature: Rankin, Delisle, Newton, Réaumur, Rømer
  • Improved unit test coverage

v1.1.1 (July 8th, 2013)

  • New physical quantity: Angle
  • Additional units of measure on Time

v1.1.0 (May 7th, 2013)

  • Add add() and subtract() methods to physical quantities
  • toString() on quantities now shows the original unit, as expected

v1.0.0 (May 7th, 2013)
