Why This Conversion Matters
This pair crosses the troy and avoirdupois mass systems. Matching words such as “ounce” or “pound” do not imply matching sizes. Exact unit relationships: 1 lb t = 12 oz t; 16 oz = 1 lb. The calculator uses the full stored factor and rounds displayed results to 12 significant digits. Display precision is not a guarantee of measurement accuracy.

Common Mistakes to Avoid
Dropping the troy qualifier or carrying a subdivision rule into the other system
A troy pound has 12 troy ounces; an avoirdupois pound has 16 avoirdupois ounces. The two ounce sizes also differ, so merely changing 12 to 16 is not a cross-system conversion.

Pro Tips
- ✓Do not apply the 16-ounce avoirdupois rule to lb t; its subdivision is 12 oz t.
- ✓Keep oz, oz t and fl oz distinct: they identify an avoirdupois mass, a troy mass and a volume.
- ✓Use the full source and destination definitions, and retain oz t or lb t wherever a troy unit is intended.
