is there a way to calculate TOTAL edge length and the l length of curves?

See the file below,i would like to know how long the the curve below is (and how to figure it out)as well as the total edge length of the one converted to a mesh.(i know the mesh one would have the same length as the curve and vice versa but i would like a a way to work it out anyway)
