Precision and rounding
The conversion uses 43560 as the multiplication factor shown on this page. StraightTools displays practical decimal precision, but a real measurement cannot be more accurate than the source value. For engineering, scientific, legal, or regulated work, preserve the precision required by the applicable standard.
Reverse conversions

Some unit names vary by country or context, especially volume, cooking measures, and digital storage. Check that the units on the source document match the definition used by the converter before relying on the result.
FAQ
