Grams into ounces, fast
Recipes are the usual culprit. A European baking site lists 200 g of chocolate, your kitchen scale or recipe card thinks in ounces, and you’re stuck doing arithmetic before you can preheat anything. This handles it in a keystroke.
Multiply by a small number and you’re done. 1 gram = 0.035274 ounces, which is just the flip side of 1 ounce = 28.3495 grams. Enter grams, get ounces. Use the dropdown to switch direction or jump to pounds and kilograms.
How the numbers line up
ounces = grams x 0.035274
or equivalently, ounces = grams / 28.3495
Both routes give the same answer because one ounce is defined as 28.349523125 grams. We round the display sensibly but keep the calculation tight, so 100 g shows as 3.527 oz rather than a lazy “about 3.5.” For mailing a parcel that’s near a postage cutoff, those extra decimals decide which rate you pay.
Handy reference points
| Grams | Ounces |
|---|---|
| 1 g | 0.035 oz |
| 10 g | 0.353 oz |
| 28.35 g | 1.000 oz |
| 50 g | 1.764 oz |
| 100 g | 3.527 oz |
| 250 g | 8.818 oz |
| 454 g | 16.01 oz |
| 500 g | 17.64 oz |
Notice the 454 g row lands almost exactly on 16 oz. That’s because 16 ounces make a pound, and a pound is 453.6 g. Half a kilo (500 g) is a touch over a US pound, which surprises people who assume they’re the same.
Three places this matters
Cooking and baking top the list. Metric recipes weigh dry goods in grams for accuracy, but US measuring tools and many older cookbooks speak ounces. Converting 125 g of flour to 4.41 oz lets you follow the recipe without guessing.
Mail and shipping come next. Postal services price small packages by weight, and the thresholds are unforgiving. A letter at 28 g versus 30 g can cross into the next price band, so if your scale reads grams and the postage chart reads ounces, you convert before you stamp.
Jewelry and precious metals are the third. A pendant might be quoted at 7 g, which is 0.247 oz. One caution here: precious metals are often sold by the troy ounce, not the standard one. A troy ounce is 31.1035 g, heavier than the 28.3495 g ounce this tool uses. For gold, silver, and platinum, make sure you know which ounce a price refers to.
A note on the “ounce” you mean
There are two ounces floating around. The avoirdupois ounce (28.3495 g) is the everyday one, used for food, mail, and body-related weights. The troy ounce (31.1035 g) is used for precious metals and gemstones. This converter uses the standard avoirdupois ounce. If you’re weighing bullion, factor in the difference.
All of it runs inside your browser. Nothing you type gets uploaded, and the page keeps converting even with the connection dropped.
FAQ
How many ounces in 100 grams?
About 3.527 oz. So 200 g is roughly 7.05 oz and 50 g is about 1.76 oz.
What’s the rough mental shortcut?
Divide grams by 28. Close enough for most kitchen work: 140 g is roughly 5 oz, and the exact value is 4.94.
Is this the troy ounce used for gold?
No. It uses the standard (avoirdupois) ounce of 28.3495 g. A troy ounce is heavier at 31.1035 g, so don’t use this for bullion pricing.
Why isn’t 500 g exactly one pound?
Because a pound is 453.6 g, not 500. Half a kilo is about 17.64 oz, slightly over a pound.
Does my data go anywhere?
It doesn’t. Every conversion is calculated on your device, so nothing is sent to a server.
