A list of the fundamental and derived SI units is also provided.
All the constant can be copied in the clipboard to be used in other programs.

Update Description:
v1.10:
- Fixed value of radius of Neptune.
- Extended Units drop down list which values are now saved at exit.
- Other minor bugs fixed, code optimization.

v1.9:
- General bugs fixed.

v1.8:
- Fixed several typos in the derived SI units.

v1.7:
- The program now saves the constants at the exit.

v1.6:
- Fixed mistake on the Magnetic flux density derived SI units.

v 1.5:
- Astronomical constants by NASA (http://sse.jpl.nasa.gov/planets/).

v 1.4:
- The Hubble constant has now the correct units.
- Added astronomical information for Neptune.

v1.3.1:
- Some users reported some difficulties while using the exponential factor "e".
- For this reason now the factor is now showed in upper case "E".

v1.3:
- New constants added (electron and proton cyclotron frequencies, classical electron radius, golden mean)
- Minor bugs fixed.
