A modern US quarter coin weighs approximately 0.20 ounces (5.67 grams). However, it’s worth noting that this weight applies to quarters minted since 1965, which have a copper-nickel clad composition. Quarters minted before 1965, containing 90% silver and 10% copper, were slightly heavier at 6.25 grams. If you’re wondering about the conversion of other units to ounces, here’s some additional information:
- There are approximately 28.35 grams in one avoirdupois ounce.
- One troy ounce, used for precious metals like silver and gold, is equal to approximately 31.1035 grams.
