Uconeer unit converter for engineers main screen annotated

The Uconeer main screen shown at approximately 2/3 scale. The layout of this screen has been carefully designed to mimimize the clicking and scrolling needed to convert units and to use the specialized conversion calculators.

The full list of categories included in Uconeer

Categories available in Uconeer engineering unit converter

Uconeer will convert units in all the basic categories, as well as in an extensive range of engineering measurements. These categories cover a total of over 450 units, and up to 5 custom units can be added in each category.

Adding Custom Units of Measurement

Adding custom units in Uconeer engineering unit converter

Additional units can be easily defined in terms of any of the units already in Uconeer (including previously added custom units). The custom units are automatically saved, but can also be exported for distribution and sharing. This allows an authorized set of custom units to be distributed to the entire office or project. Custom units can of course also be edited or deleted. Here is an article on how to calculate your own conversion factors.

Using Favorite Conversions

Editing favorites units in Uconeer engineering unit converter

Up to 12 unit conversions can be set as Favorites, enabling them to be selected with only two clicks. The Favorites can be sorted manually, alphabetically or dynamically to suit your way of working. This is the fastest way to convert units you use frequently.

Converting between Mass and Volumetric Flowrates for Gases

Converting between mass and volumetric flows for gases

This special conversion calculator will convert between mass and volumetric flowrates for gases using a variety of methods for setting the gas density. Data for 16 commonly used gases is included. A variety of standard gas conditions such as IUPAC, NIST, European (Metric), SPE, EGIA and OPEC are included, plus the capability to set up your own custom standard conditions. Volumetric flowrates can be converted from one basis to another (for example from SCFM to normal meter cubed per hour) using the mass flow as an intermediate step.

A similar, but simpler, calculator is included for liquid flowrates.

Working with Feet, Inches and Fractional Inches

Converting between decimal lengths and feet, inches and fractional inches

This screenshot from yet another special conversion calculator shows a conversion from a decimal length to feet, inches and fractional inches, but Uconeer can also convert measurements in the opposite direction. The rounding precision can be set from 1/4 to 1/128 inch.

Reynolds Number Calculator for Flow in Round Pipes

Calculator for Reynolds Number in pipes using mixed units

The Reynolds Number Calculator will calculate Re for flow in round pipes with mixed units and using velocity, mass flowrate or volumetric flowrate as the basis.

Hardness Equivalents for Steel

Steel Hardness Equivalents in Brinell, EQUOtip, Knoop, Rockwell, Shore,  Vickers scales and Tensile Strength

The hardness conversion calculator will give carbon steel hardness equivalents in units from the Brinell, EQUOtip, Knoop, Rockwell, Shore and Vickers scales as well as convert units of Tensile Strength. Includes range checking to indicate permissable measurement values for each combination.

Converting between Dynamic and Kinematic Viscosity

Converting between Dynamic and Kinematic Viscosity

Although Dynamic Viscosity and Kinematic Viscosity each have their own category in Uconeer, they are related to each other directly through the fluid density. This conversion calculator gives you the link between the two categories. It includes units like poise (P), centipoise (cP), pascal.seconds (Pa.s), stokes, centistokes and most other viscosity units used by engineers.

Values of the Universal Gas Constant "R"

Convert Universal Gas Constant into different units

This calculator will determine the value of the Universal Gas Constant "R" in any combination of units. The energy term can be entered either as an energy unit directly, or by entering pressure and volume units. And if we have not included the Energy, Pressure or Volume units you need, you can easily add them yourself.

Tables of values of the Universal Gas Constant with the most frequently used combinations of units have been prepared from Uconeer for those who simply want to look up a particular value of "R" and don't want to download the complete program (but then you miss out on all the other great features of the Uconeer units conversion program).
