# Command: unit_conversion

NEST HelpDesk | Command Index | NEST Quick Reference

Name:

    unit_conversion - Conversion factors for SI units.

Examples:

      The following call always simulates 1000 ms of network time,

      1000 ms Simulate

Description:

      Some SLI functions and tools expect numerical arguments which carry SI units.
      function/tool	 expected unit
      ----------------------------------
      Simulate	 ms
      current generators   pA
      voltmeters	 mV
      ac_generator	 Hz

      As SLI does not know any unit conversion scheme, numerical values
      need to be specified in the appropriate units. However, it improves
      readability, if a hint to the unit is specified in the program code,
      such as "333 pA", instead of just "333".
      Furthermore, it may be convenient to have other units converted to the
      ones expected by the routines. (For example, "ms" converts from milliseconds
      to timesteps, taking into account the current network resolution, see
      example below.)

      The following conversion factors are known (developers: please add others in
      nest-init.sli as required):
      ms, pA, mV, Hz, spikes

Availability:

    This is just a description. unit_conversion is no SLI command.
