Показано, что для создания науки о величинах, работы компьютерных программ и искусственного интеллекта нужна классификация величин по смысловым признакам. Цель статьи — показать непригодность единиц измерения и их размерностей для идентификации величин и необходимость разработки иного способа классификации величин по их смыслу. На примерах проверяется возможность передать смысл физической величины при помощи возведенной в некоторую степень размерности или единицы измерения основной величины. Все рассмотренные примеры дали отрицательные результаты. Выявлена особенность величины „длина“ в вопросе образования размерности производной величины путем возведения размерности основной величины в степень. Эта особенность объясняется возможностью объединения длины с различными направлениями в пространстве. Возведение размерности длины в степень подменяет операции с векторами. Случаи возведения в степень других размерностей являются бессмысленными фрагментами и не соответствуют какой-либо величине, принятой в науке. Рекомендуется направить усилия на изучение и формализацию связей между самими величинами, объединив подходы в таких науках, как метрология, физика, математика, теория познания.</p></abstract><trans-abstract xml:lang="en"><p>The possibility of expressing the meaning of a physical quantity using dimension and unit of measurement is explored. It is shown that in order to create a science of quantities, for the operation of computer programs and artificial intelligence with the meaning of quantities, a classification of quantities according to semantic criteria is needed. The purpose of the article is to show the unsuitability of units of measurement and their dimensions for identifying quantities and the need to develop a different way of classifying quantities according to their meaning. Using examples, the possibility to convey the meaning of a physical quantity by raising dimension or unit of measurement of the basic quantity to a certain power is tested. All considered examples gives negative results. A peculiarity of the quantity “length” has been revealed in the matter of forming the dimension of a derivative quantity by raising the dimension of the main quantity to a power. This feature is explained by the possibility of combining length with different directions in space. Raising the length dimension to a power replaces operations with vectors. Cases of exponentiation of other dimensions are meaningless fragments and do not correspond to any value accepted in science. It is recommended to direct efforts to study and formalize the connections between the quantities themselves, combining the approaches of such sciences as metrology, physics, mathematics, and theory of knowledge.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>размерность величины</kwd><kwd>единица измерения</kwd><kwd>система величин</kwd><kwd>вектор</kwd><kwd>физический смысл</kwd><kwd>искусственный интеллект</kwd><kwd>определительное уравнение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>quantity dimension</kwd><kwd>measurement units</kwd><kwd>system of quantities</kwd><kwd>vector</kwd><kwd>physical meaning</kwd><kwd>artificial intelligence</kwd><kwd>defining equation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bridgman P.
