Why this conversion matters in chemistry
Take vacuum-system controller readouts. A turbopump rated for 2 × 10⁻⁷ Pa ultimate base pressure displays as 2 × 10⁻⁹ mbar on the ion-gauge controller — the same vacuum expressed in different units. Many physics-lab vacuum controllers print both scales side by side because the 100:1 ratio is the routine bridge across SI and the older European mbar convention. The ratio of 0.01 mbar per Pa comes from 1 mbar = 0.001 bar = 100 Pa. What it really is: a unit step between SI vendor specifications and mbar-based vacuum equipment.
