No. The standard-section figure is a study assumption, not a guarantee for every surveyed parcel. BLM describes sections as usually containing 640 acres. In an exercise that expressly assumes a regular 640-acre section, one quarter is 640 x 1/4 = 160 acres.

For an actual property, do not replace the relevant survey and land records with that memorized number. If recorded acreage differs from the classroom figure, the difference calls for checking the records with a qualified professional, not rewriting the description. This answer does not determine a property's boundaries or ownership.

The acreage worksheet states its assumptions before each calculation. Our legal-descriptions guide explains how a land description differs from a street address or parcel ID.
