Moving to Particle Edit mode after setting up hair particle length does not preserve the set up length. See attached picture.

  1. create hair particle setup
  2. set hair length to 0.5
  3. go to Particle Edit mode

Expected result : hair length in particle edit mode is of equivalent size as what was setup
Actual result : hair length in particle edit mode is much longer that what has been set up

Please attach a simple .blend file to reproduce the problem, it is probably related to specific particle settings. With a quick setup here I don't see the problem.

File now properly attached to ticket.

I didn't apply the scale transform which may have been the source of the problem, however I now tried to apply it and the problem still exists.

It is a Children settings thing. You can see Children while Particle Edit. In Particle Edit mode look for the option in first tab of Properties Editor.

Ah ok, chlidren hair lenght was < 1, setting it to 1 then both Particle Edit and Object mode have the same hair length, controlled by emitter hair length. Ok so I guess this is not a bug, sorry, ticket can be closed.
