Real-world example — Adjacent small-scale precision
One imperial quart equals 1,000 milliliters — the standard sub-millimeter precision conversion that materials engineers use whenever they switch between bulk material thickness specs (larger unit) and surface-finish characteristics (smaller unit).
1 qt × 1136.5225 = 1136.5225 mL
Real-world example — Adjacent metric sub-units
One imperial quart equals 1,000 milliliters. Engineers move between these scales constantly: PCB feature sizes in the larger unit, wire-bond diameters in the smaller.
1 qt × 1136.5225 = 1136.5225 mL
