Most wrong answers come from mixing unit systems, rounding too early, or choosing a unit that looks similar but means something different.
- Do not use a length conversion factor for area. Area units use squared relationships.
- Do not mix floor area, land area, usable area, and rentable area without keeping the source definition.
- Avoid rounding each room, parcel, or surface separately when you need an accurate total.
