Get the correct (unprojected) Length of Features/ Shapes

I now have some polylines where I want to read out the length. But due to projections the length of these features may is corrupt (you know: a line at the equator has another length as the same line on one of the poles).

I want to read the length of ANY feature (platform independently) and convert it to the real/ original length in the unit of my choice (e.g. meter).

I think there must exist an solition for this but I can't find anything interesting to this.
Thanks for help, ideas and advice.
