Task: Question Answering
Input (English): passage: Metrication (or metrification) is the process of introducing the International System of Units, also known as SI units or the metric system, to replace a jurisdiction's traditional measuring units. Although all U.S. customary units have been redefined in terms of SI units, as of 2018 the United States is one of only seven countries, including Myanmar (Burma), Liberia, Palau, the Marshall Islands, the Federated States of Micronesia, and Samoa that have not officially adopted the metric system as the primary means of weights and measures. However, both Myanmar and Liberia are reportedly essentially metric, even without official legislation in effect, while Palau, Micronesia, and the Marshall Islands are all administered by the United States under the Compact of Free Association.
 question: is the united states on the metric system?
Output (English): No
