    Does anyone know of a method or add-on for SI formatting SI units in
    Excel?

  2. Hello WayneL,

    are you talking about SI-units like m, kg, s or do you think on the
    SI-prefixes p, n, u, m, k, ... which are numeric multipliers.

  4. Wouldn't it be nice if Excel could display '1n', instead of '1.00E-9' or
    worse '0.000000001'? And it would be great if I could type 4M7 and have
    it interpreted as 4.7 million.

    I'm surprised this is so rarely done. It not hard or anything. I only
    know of gnuplot and spice that use some of this, and spice even gets it
    wrong, confusing M(ega) and m(illi). Pathetic.

  5. IMO it would be reasonably easy to do in VBA.

    Does excel support "custom" formats? You could write a little parser in
    VBA, but I don't know of anything OTS.

    Good Luck

    All the PSpice utilities my oldest son wrote for me can accept entries
    like "8.46p" etc.

    I believe it can be done in Excel as well, but I couldn't find it.

    Mark/qrk, Didn't you show me how to do that once? Or was it someone
    else?

  9. When you enter the field to update it you need to erase the contents. Then
    when you leave the field you parse the contents and rewrite as needed.
