Volume conversions come up constantly outside of a classroom. Recipes written for a US audience use cups and tablespoons while international ones use metric measurements; travel and navigation mix miles, kilometers, and nautical units depending on the country and mode of transport; and technical fields like engineering, medicine, and manufacturing often require converting between systems to match a spec sheet, a prescription, or a purchase order.
