Note: The FACTOR VALUES in this table have been rounded to 2 decimal places to the
right of the decimal. Metric values in the literature are stated as 6 to 11 decimal places to
the right of the decimal. As an example the metric factor for pounds : kilograms, there are
(1 lb ÷ 2.204 kilograms / pound =) 0.45372050816 kilograms in one pound. In this table
that value has been rounded to 2 places to the right of the decimal and stated as 0.45. This
table will serve to explain metric measurements and conversions between English and
metric for the problems in this chapter.
