Units and unit conversions
- Extensive units capabilities and conversions between complex combinations of units.
- Units can be assigned to input or output quantities, e.g., for auto-generating codes such as MATLAB®, C, Fortran, ...
- Integrated with commands such as Evaluate, Solve, ODE, ...
- Set units with commands such as Input, Output, Constant ...
- Calculate numerical conversion factors with the ConvertUnits command.
- Updated with NIST/CODATA data.
