How to Convert 571 Grams to Ounces
Step 1: Use the Exact Conversion Factor
Both grams and ounces measure mass (not volume), so there’s no density to look up — the conversion is a single, fixed multiplication. The internationally defined relationship is:
Step 2: Apply the Formula to 571 Grams
To turn 571 grams into ounces, divide by the grams-per-ounce factor (or, equivalently, multiply by 0.03527396195):
Quick mental math: Dividing by 28.35 is a hassle in your head. A useful trick: divide grams by 28 for a fast estimate, then add about 1.2 %. For 571 g that gives roughly 20.14 oz — close to the exact answer.

2. Plug in 20.14 oz:
Small rounding differences appear because the displayed ounce value is truncated to two decimals — the calculator above uses the full-precision factor and will round-trip exactly.
Step 4: Decide Which Ounce You Need
Not every “ounce” is the same unit. Match the ounce to the situation:
- Standard ounce (28.349523125 g) — food, kitchen scales, postage, retail, nutrition labels. Sometimes called the “avoirdupois” ounce in formal references. This is what 571 g = 20.14 oz refers to by default.
- Troy ounce (31.1034768 g) — gold, silver, platinum, palladium. 571 g = 18.3581 troy oz.
- Fluid ounce — a volume unit, not a weight. Don’t mix it up with the standard mass ounce.
Rounding rules used on this page: Ounces are displayed to two decimal places for everyday use and four decimals for precision. Troy ounces are shown to four decimals because precious metals trade at fine resolution.

Five hundred seventy-one Grams in Context
Weight class: substantial
571 grams is best described as about substantial weight (~600 g). On a kitchen scale you’ll see a reading of 571 g; on an American postal scale or imperial scale the same item registers as 20.14 oz. That difference is purely the unit you’re reading — the mass itself is identical.
For postal shipping in the US, scales typically display ounces; international labels usually require grams. Knowing both removes any guesswork at the counter.
If you’re working with bullion, the same 571 grams equals 18.3581 troy ounces. A troy ounce is about 9.7 % heavier than a standard ounce, which is why precious-metal weights look smaller in troy-ounce form for the same gram value.
