- **Sections**: Your inputs; Bring a worksheet question.
  - Convert an actual measured area, not an abstract number or a survey name. This uses international-foot area units. Historical U.S. survey-foot measurements use a different factor and need their original basis. One square foot is 1/43,560 acre; one square mile is 640 acres.
  - NIST: area unit conversion factors.
  - Area amount × selected acres-per-unit factor = acres

### Ask about a working tool | OGML Tools
