Conversion
a.
Requirements for Conversion. To convert from one system to another, a
knowledge of equivalent values between these two systems is necessary.
Table 4 provides a list of equivalent values between the two systems for
linear measurements equal to or greater than one inch.
Table 5 on the
following page provides the metric equivalents of linear measurements of
less than an inch.
