Highlights

With the help of uomConvert a host application can do the following:

• Convert values accurately from one Unit of Measure to another chosen from an extensive range in a variety of domains (e.g. length, volume, etc.). Over 30 built-in Domains and nearly 1000 Units of Measure (UOMs) are supported.
• Format returned values according to user-defined edit patterns.
• Navigate the simple supplied object model to retrieve lists of supported Domains, their corresponding Units of Measure and their properties including display names, symbols and conversion factors. This allows a developer to offer the application user the capability of viewing program data in any of a wide range of units without the need to specifically know any details of the individual units (the number of units available for each supported domain can be found below). The sample application shows how this may be done with just a few lines of code.
• Add new custom Units of Measure to the supported domains so that they can be used in the conversion functions allowing conversions between the custom UOMs and any of the built-in UOMs.
• Add whole new custom domains and corresponding sets of UOMs.
• Accurately retrieve values for a range of mathematical and scientific constants.

Once the component has been installed on the developer workstation, any development tool that supports the containment of ActiveX component can reference it. The developer can then access all of the uomConvert methods (functions) and properties from within their code. The User Guide contains example code for Microsoft Visual Basic or VBA (Visual Basic for Applications, as supported by Microsoft Word, Excel and Access).

This is a 32-bit in-process OLE server DLL which may be used on any 32-bit Windows platform (NT/2000 or 95/98/Me).

It includes a sample Visual Basic project which demonstrates how to call the component functions. The project builds a full stand-alone Unit of Measure conversion program.

It supports the following built-in domains (numbers in brackets indicate the number of units of measure supported for each):

• Acceleration (15)
• Angle (13)
• Angular Acceleration (7)
• Angular Velocity (9)
• Area (83)
• Density (29)
• Electric Capacitance (13)
• Electric Charge (15)
• Electric Conductance (12)
• Electric Current (13)
• Electric Field Strength (13)
• Electric Inductance (12)
• Electric Potential (14)
• Electric Resistance (12)
• Energy (57)
• Force (19)
• Length (99)
• Luminance (14)
• Luminous Intensity (9)
• Magnetic Field Strength (6)
• Magnetic Flux (4)
• Mass (86)
• Power (65)
• Pressure (50)
• Temperature (4)
• Thermal Conductivity (11)
• Thermal Heat Capacity (9)
• Time (40)
• Torque (15)
• Velocity (37)
• Viscosity - Dynamic (18)
• Viscosity - Kinetic (20)
• Volume (107)
• Volume Flow (40)

uomConvert incorporates full error-handling features giving the developer full control over how exceptions are handled. By default, no error messages are displayed to the user by uomConvert. It is left to the developer to decide when to display messages and when not to. It is possible, however, to programmatically switch on and off automatic error display using the DisplayErrors property of the supplied Convert object.
