Common questions
Are these US survey feet?
No. The calculator uses the international foot. For historical survey measurements, confirm the unit definition used by the source.
Why is the result rounded?
Repeating decimals are shortened for readability. Keep adequate precision for engineering or surveying work.
Can I enter zero?
Yes. Zero converts to zero. Negative lengths are rejected by this tool.
