Switch between metric and imperial weight units using this simple guide to convert grams to ounces. Useful for recipes, shipping, product specifications, and educational use
Grams to ounces conversion helps you switch between two common units of weight.
If you're following a recipe, shipping a package, or studying science, converting grams to ounces can be useful when the source material uses different measurement systems.
A gram (g) is a metric unit of mass. It's part of the International System of Units (SI) and is commonly used around the world for measuring light weights used in cooking, nutrition, science, and daily products.
An ounce (oz) is an imperial unit of weight mainly used in the United States. It's often found in grocery packaging, recipes, and postal services.
To convert grams into ounces, divide the number of grams by 28.3495.
Formula: Ounces = Grams/28.3495
Example: Converting 100 Grams to Ounces
Suppose you are analyzing the weight of a small protein snack bar that is labeled as 100 grams, and you wish to determine its equivalent weight in ounces.
We use the standard conversion factor:
1 ounce = 28.3495 grams
To convert, apply the formula:
Ounces = Grams / 28.3495
Now substitute: Ounces = 100 / 28.3495 = 3.527
So, 100 grams is approximately 3.53 ounces
A troy ounce is a unit of mass used primarily to measure precious metals like gold, silver, platinum, and palladium.
It differs from the standard (avoirdupois) ounce used in everyday measurements.
This makes a troy ounce heavier than a regular ounce.
If you're converting grams to ounces for gold coins, bullion, or jewelry, it's important to use the troy ounce, not the standard ounce.
Using the wrong unit can lead to incorrect pricing or misunderstandings in trade and valuation.
Example:
You have a gold bar that weighs 62.2 grams.
To convert to troy ounces:
Troy Ounces = 62.2 / 31.1035 = 2 troy ounces
| Grams (g) | Ounces (oz) |
|---|---|
| 1 g | 0.035 oz |
| 5 g | 0.176 oz |
| 10 g | 0.353 oz |
| 50 g | 1.764 oz |
| 100 g | 3.527 oz |
| 200 g | 7.055 oz |
| 500 g | 17.637 oz |
| 1000 g | 35.274 oz |
Gold is measured using the troy ounce, not the regular ounce. 1 troy ounce of gold = 31.1035 grams. This is the global standard used by jewellers, investors, and bullion dealers.
If you're using the standard (avoirdupois) ounce, which is common in cooking and everyday items: 1 ounce = 28.3495 grams. This unit is used mainly in the United States and other countries for measuring food, body weight, and shipping.
A troy ounce = 31.1035 grams. This unit is older and specifically used for precious metals like gold, silver, and platinum.
Silver, like gold, is also weighed in troy ounces. 1 troy ounce of silver = 31.1035 grams. Whether you're buying silver bars or coins, this conversion applies globally.
