Program Description

Uconeer is a professional engineering unit conversion software package for Windows (See here for Mac support). It includes a wide range of technical measurement categories required by engineers, but it excludes the archaic and esoteric units that clutter the menus of other programs. However, if we have left out the particular measurement units that you do need you can add them in yourself, allowing you to work with those that are particular to your industry or location.

• Replace your paper-based tables with this free-to-try software. Uconeer includes conversion factors for all the standard categories like Acceleration, Area, Force, Fuel Consumption, Length, Mass, Power, Pressure, Temperature, Velocity (Speed) and Volume.
  
  
• In addition to the standard categories Uconeer includes conversion factors for engineering categories like Diffusivity, Enthalpy, Entropy, Fouling Factor, Heat Capacity, Heat Transfer Coefficient, Moment of Inertia, Pressure Drop per Unit Length, Stress, Surface Tension, Thermal Conductivity, Valve Sizing Coefficient, Friction Factor, Torque and Viscosity. See full list of measurement categories.
  
  
• Includes only the practical engineering unit conversion factors in each category, making them quick and easy to select. Covers the SI, Metric, Imperial, British Engineering and US Customary systems of measurement. And you can add in up to 5 custom units in each category. Custom units can be exported, merged and imported to facilitate standardization of conversion factors for an office or project. (Screenshot of custom units editor). Here is an article on how to calculate your own conversion factors.
  
  
• Nominate up to 12 frequently used conversions as your Favorites for instant access. (Screenshot of favorites editor)
  
  
• IAPWS IF-97 based Steam Tables giving 18 temperature and pressure dependent properties over the range from -100°C to 800°C up to 1000 bar abs, and some extend up to 2000°C at pressures below 500 bar abs. Also includes 16 fixed properties. Use all the engineering units built into Uconeer, plus your custom units. Calculate properties when temperature and pressure are known, or search for specific values of enthalpy, entropy or density. Includes wet steam properties. Set local atmospheric pressure for accurate gauge pressures. More details here.
  
  
• Dedicated Reynolds Number Calculator for pipe flow allows mixed systems of measurement, as well as the option of using velocity, mass flowrate or volumetric flowrate as the flow basis. Viscosity can be specified as dynamic or kinematic. (See Reynolds Number Calculator in action)
  
  
• Convert between density and specific volume.
  
  
• Convert decimal lengths directly to and from lengths in feet, inches and fractional inches. (See feet, inches and fractional inches example)
  
  
• Convert between dynamic viscosity and kinematic viscosity. (Example screenshot)
  
  
• Hardness equivalents calculator includes Brinell, Knoop, EQUOtip (tm), Rockwell, Shore Scleroscope, Tensile Strength and Vickers hardness scales for steels. (Screenshot of steel hardness equivalents calculator)
  
  
• Flowrate conversion calculator between volumetric and mass flowrate for liquids or gases. Includes automatic estimation of gas density from molecular mass. (See gas flowrate example)
  
  
• Universal Gas Constant "R" Calculator works in any combination of units (including your custom units), which can be based on Energy or Pressure x Volume. (Screenshot of Universal Gas Constant calculator)
  
  
• Flexible formatting of output, including scientific and engineering notation.
  
  
• Full support for clipboard, with clipboard contents always shown on screen. Allows you to easily import values, and to paste results and unit labels into other programs.
  
  
• Online calculator during data entry.
  
  
• "Recently-used" list ensures that the categories which you use regularly are available with a single click.
  
  
• Small download size - only 2.5 Mb. Totally self-contained with no dependence on any frameworks, run-time libraries or DLLs.
  
  
• Full install and uninstall utilities included.
