A modius is an old-fashioned way of measuring things, like a bushel. It was also used to measure land, but we're not exactly sure how much it was.
A modius is a unit of measurement used in ancient Rome. It was used to measure things like grain and other dry goods. It was also used to measure land, but the exact amount it represented is uncertain.
For example, if a farmer had a modius of wheat, it would be equivalent to a bushel of wheat. If a landowner had a modius of land, it would represent an uncertain amount of land.
