§  1.19   Use of metric units required.

   Where parenthesized English units accompany metric units throughout
   this chapter, and the two figures are not precisely equivalent, the
   metric unit shall be considered the sole requirement; except, however,
   that the use of metric paper sizes is not currently required, and
   compliance with the English unit shall be considered sufficient when
   the Commission form requests that data showing compliance with that
   particular standard be submitted in English units.
