Paste 10 mm, 19 mm and 25.4 mm, one measurement per line, convert to inches and export CSV. I built Convertisseur Mesures, a free French/English converter that also compares 1/8, 1/16, 1/32 and 1/64 inch steps with their signed error in millimetres. Set an approximation limit and share a single result by link. Calculations run locally in your browser without an account. The limit concerns approximation, not part compliance.
