Why is the inch (US survey) different from the international inch?

The inch (US survey) is a legacy surveying unit defined exactly as 100/3937 meters, used historically for U.S. geodetic control and cadastral surveys, differing slightly from the international inch.

What is a picometer used for?

A picometer is an SI unit equal to 10⁻¹² meters, commonly used to measure extremely small distances such as atomic bond lengths and interatomic spacings.

Can this tool convert modern survey inches?

This tool specifically converts the inch (US survey), a legacy unit, to picometers and may not be intended for the international inch without additional context.
