Ounces to Grams Converter

About Weight Conversion

Converting ounces to grams? If you cook, bake, or work with measurements, you'll need this conversion all the time. Ounces are standard in the US, but most of the world uses grams. When you're following recipes, shopping online, or working with ingredients, you'll constantly need to switch between units.

An ounce is 1/16 of a pound, or exactly 28.3495 grams (most people use 28.35 for simplicity). That's the key number—multiply ounces by 28.35 to get grams. Four ounces is 113.4 grams. Eight ounces (half a pound) is 226.8 grams. Simple enough, but doing the math repeatedly gets old fast.

Grams are part of the metric system, used everywhere except the US for most applications. One gram is 1/1000 of a kilogram. It's precise, works cleanly with decimals, and is the standard for cooking, science, and everyday measurements in most countries. Professional kitchens and bakers worldwide weigh everything in grams because it's more accurate than volume measurements.

Cooking is where this conversion comes up constantly. American recipes often list ingredients in ounces, but if you have a metric kitchen scale or you're trying to follow an international recipe that mixes units, you need to convert. A recipe calling for 4 ounces of chocolate needs 113.4 grams. That might seem close to 115 grams, but for baking, those small differences matter.

Baking especially requires precision. A recipe might ask for 6 ounces of flour, which is about 170 grams. But if your scale only shows grams, you need to know the exact conversion. Professional bakers prefer weighing in grams because it's more accurate than using measuring cups. Four ounces is always 113.4 grams, but a "cup" of flour can weigh different amounts depending on how you measure it.

International recipes are a nightmare without conversions. You might find a recipe that lists butter in ounces (like 8 ounces, which is a standard stick in the US), but you're using European butter that comes in grams. Eight ounces equals 226.8 grams. Or you're scaling a recipe—doubling it means 16 ounces becomes 32 ounces, which is 907.2 grams. Converting helps you use recipes from anywhere in the world.

Shopping online across borders requires this constantly. Products from different countries list weights in different units. That 12-ounce package of coffee might be listed as 340 grams in an international store. They're the same weight, but if you're used to ounces, understanding grams helps you compare sizes and prices accurately.

Package weights and shipping involve this too. International shipping often uses grams, but US postal rates might use ounces. A package that's 16 ounces (one pound) is 453.6 grams. If you're shipping internationally, knowing both units helps you calculate costs and understand weight limits. Some shipping services charge different rates based on weight brackets, so accurate conversion matters.

Nutrition and diet tracking uses grams frequently. Nutritional labels might list protein, carbs, or other nutrients in grams, but you're thinking in ounces or following a plan that uses ounces. Four ounces of chicken breast is about 113 grams and contains roughly 35 grams of protein. Understanding the conversion helps you track accurately and meet your nutritional goals.

Jewelry and precious metals are often weighed in both units. Silver and gold can be priced per ounce or per gram. An ounce of silver is 31.1 grams (troy ounces are slightly different from regular ounces). Understanding both helps when you're buying, selling, or comparing prices across different markets or regions.

Coffee and specialty beverages use ounces in the US but grams elsewhere. That 12-ounce bag of coffee beans is 340 grams. Espresso shots are measured in grams in most professional settings, but American recipes might use ounces. A double shot might be 2 ounces or 57 grams—same thing, different numbers. Converting helps whether you're brewing at home or ordering at a cafe.

Portion sizes and meal planning involve this too. Pre-packaged foods often list serving sizes in ounces, but you might want to track in grams. A 6-ounce serving of meat is 170 grams. Converting helps you plan meals, track calories, and understand portion sizes regardless of which unit you prefer to think in.

Even postal and mail services require this. Letter weights are often given in ounces in the US, but international mail might use grams. A letter weighing more than 1 ounce (28.35 grams) might need extra postage depending on where it's going. Converting helps you figure out postage before you get to the post office.
