HC Deb 20 November 1979 vol 974 c111W
22. Mr. Sainsbury

asked the Secretary of State for Education and Science what proportion of children is taught mathematics and science with imperial measurements, what proportion with metric measurements and what proportion is taught using both systems of measurement.

Mr. Macfarlane

This information is not available. The DES issued advice in 1974 that teaching should be conducted principally in metric terms while maintaining general familiarity with imperial units, and this still stands.
