The government allowed geodesists and surveyors to keep using the foot of 1893, which became known as the U.S. survey foot, in deference to the historical measurements they relied on, with the understanding that they would eventually embrace the new foot.

Whether they embrace the new one or not, the old foot will be obsolete as of Jan. 1, 2023, according to the National Institute of Standards and Technology, the agency within the Department of Commerce with the authority to fix weights and measures for the U.S.“At that point, we will discourage everyone from using the U.S. survey foot,” said Elizabeth Benham, the institute’s metric program coordinator.
