An ounce can mean a few different things, so “how much is an ounce?” depends on whether you mean weight or money (and if money, of what).

Basic weight meaning

  • In everyday U.S. use, 1 ounce (oz) is a unit of weight in the avoirdupois system.
  • 1 ounce ≈ 28.35 grams.
  • There are 16 ounces in 1 pound.

When people talk about food labels, drinks, or most store items in the U.S., they almost always mean this regular ounce of about 28 grams.

Troy ounce (for precious metals)

There’s also a different ounce used almost only for precious metals like gold and silver:

  • 1 troy ounce ≈ 31.1 grams.
  • Gold, silver, platinum, etc. are typically quoted in price per troy ounce , not per regular ounce.

So if you see a “price per ounce” for gold or silver on finance sites, assume they mean troy ounces.

How much is an ounce of gold right now?

As of late January 2026, gold is trading around about 4,900–5,000 U.S. dollars per troy ounce, and has been near record highs this month.

That means:

  • 1 troy ounce of gold ≈ 4,900–5,000 USD (very roughly, and it changes minute by minute).
  • Prices can move by tens of dollars (or more) in a single day, so any number you see is only a snapshot, not a fixed value.

If you meant a different “ounce” (like an ounce of silver, an ounce of weed, or “price per ounce” in a grocery or forum context), tell me which one and I can tailor the explanation.
