A big part of the NIST's job is providing standard samples so everyone can measure accurately. From weights of ingredients, to determining exact compositions of food, pharmaceuticals, drinking water, etc. its all measured relative to a NIST standard. Every scale you've ever used was calibrated against a weight that several steps back was ultimately calibrated against a NIST standard. Without a good standard, it's basically impossible to accurately measure anything.
