Why this conversion matters in chemistry
DFT geometry-optimization output and single-crystal refinement reports tabulate bond lengths in picometers — 154 pm for an sp³ C–C, 109 pm for a C–H. The benchtop ruler reads in centimeters. The ten billion-fold gap is the routine illustration in any introductory physical-chemistry course of how far the Schrödinger-equation scale sits from the bench. A factor of 10¹⁰ pm per cm falls cleanly out of 1 cm = 10⁻² m and 1 pm = 10⁻¹² m. The conversion is the bookkeeping step bridging laboratory-observable lengths and the per-atom geometry calculations expect.
