The actual unit Aristotle used was the &quot;mna&quot;. A mna was 100x as heavy as a drachma. According to Wikipedia (which is always right except when it&#x27;s wrong) the most commonly used standard in ancient Greece made a drachma weigh about 4.3g, in which case a mna would be about 430g, compared with 454g for a pound weight. So &quot;pound&quot; or &quot;lb&quot; is a pretty good translation for &quot;mna&quot;.<p>(The &quot;mna&quot; has rough equivalents in other ancient Near Eastern cultures. There&#x27;s at least one &quot;mina&quot; in the New Testament, and in the famous &quot;writing on the wall&quot; at Belshazzar&#x27;s feast -- MENE MENE TEKEL PHARSIN -- &quot;mene&quot; is basically the same word as &quot;mna&quot;.)
