Exact Values for Capacity & Mass
All of the derived values on this page should be exact... unless my arithmetic or my source documents are in error. My source is the Weights and Measures Division of the National Institute of Standards and Technology (NIST), a federal agency within the U.S. Commerce Departments Technology Administration.
