What is an acre (US survey)?

It is a land area unit based on the U.S. survey foot and defined as 43,560 square U.S. survey feet, slightly larger than the international acre.

Why convert acres to square inches?

Converting large land areas into square inches helps in detailed engineering, manufacturing, or printing dimensions where smaller area units are necessary.

Is the U.S. survey acre the same as an international acre?

No, the U.S. survey acre is slightly larger due to its definition using the U.S. survey foot rather than the international foot.
