Metric Units of Length

Since the Mendenhall Order of 1893,
the U.S. yard and pound and all units derived from them
have been defined in terms of the metric units of length and mass,
the meter (m) and the kilogram (kg);
since 1959 these values are 1 yd = 0.9144 m and 1 lb = 0.45359237 kg.

In the United States, the older definition of the yard as 3,600/3,937 m
is still used for surveying, the corresponding foot (1,200/3,937 m) being
known as the survey foot.
