Many finite element analysis (FEA) solvers and other engineering software do not check the units of measure provided for their calculations.
It is up to the user to ensure the problem is described in a consistent system such that all derived units can be expressed in terms of the base units.
The correct unit is often unintuitive and mistakes can happen during conversions.
This tool performs the dimensional analysis and conversions required to help you define your problem using a consistent system of units.

Unit library
The following is a list of units and abreviations recognized by this utility in any input box.
Standard prefixes
may be used with most units.
The units below may be combined to form any compound unit.
For example, mW/(cm^2*degC)
Definition of consistent unit system
This section establishes the consistent unit system used in the sections that follow.
Edit the fields below to define the units for your engineering model.
Units may be specified by name or by combination of other units;
for example, lbf*s^2/in is an awkward but valid unit of Mass.
Specify a reference unit that you would like to convert to or from.
The reference may be any combination of units and prefixes recognized by this utility, for example ksi*in^0.5 for stress intensity.
The corresponding unit within your consistent system will be automatically identified.
Values entered in the box below the Reference unit will be converted and shown below the Consistent unit.
Also, any values entered in the box below the Consistent unit will be converted back to the Reference unit.
Pro-tip: Values entered in the box below the Reference unit may include formulas to be evaluated, such as 2 atm * 3.4 ft^2
