This dual-unit labeling is uniquely American, arising from the nation's simultaneous use of Imperial units for commerce and metric units for nutrition science. European labels use grams throughout. The American label is a daily reminder that the US straddles two measurement worlds, switching between them on every trip to the grocery store.
