How to Convert Grams to Ounces

Grams and ounces are both units of weight. Grams belong to the metric system, which is used in most countries around the world. Ounces belong to the imperial system, which is common in the United States. When you need to switch between the two, you use a simple math formula. For other metric-to-imperial weight conversions, our Kg To Lbs Calculator handles kilograms and pounds.

The Conversion Formula

One ounce equals exactly 28.349523125 grams. To convert grams to ounces, divide the number of grams by 28.349523125. To go the other way and convert ounces to grams, multiply the number of ounces by 28.349523125.

Ounces = Grams ÷ 28.349523125

For example, 100 grams divided by 28.349523125 equals about 3.5274 ounces.

When You Need This Conversion

This conversion comes up often in cooking, shipping, science projects, and everyday shopping. A recipe from another country might list ingredients in grams, but your kitchen scale only shows ounces. You can pair this converter with our Recipe Cost Calculator to price out dishes that mix metric and imperial measurements. A package label might show weight in grams while you think in ounces — if you are preparing shipments, our Volumetric Weight Calculator can also help you figure out dimensional weight for carriers. Knowing how to switch between the two makes these tasks easy.

Grams vs. Ounces at a Glance

A gram is a small unit of weight. A paperclip weighs about one gram. An ounce is bigger — it takes about 28.35 grams to make one ounce. There are 16 ounces in one pound, so pounds and ounces work together in the imperial system just like grams and kilograms work together in the metric system. If you work with other unit types beyond weight, tools like our Cm To Inches Calculator, Meters to Feet Calculator, and Volume Conversion Calculator cover length and volume conversions. For calculations that involve both weight and volume, our Density Calculator and Mass Calculator can help you relate the two.

Tips for Accurate Conversions

Always use the exact conversion factor of 28.349523125 grams per ounce when precision matters. Rounding to 28.35 is fine for cooking, but science and trade often need more exact numbers. The calculator above lets you choose how many significant figures you want so you get the right level of detail for your task. If you are tracking nutrition and need to weigh food in the right units, our Macro Calculator and Calorie Calculator can put those weights to use once you have them converted.
