Convert Grams to Ounces instantly with an exact, accurate formula -- no sign-up, no ads blocking the result.
This tool converts a weight measurement in Grams into its exact equivalent in Ounces, using the fixed factor 0.03527396. Weight (more precisely, mass) conversions come up constantly across cooking, shipping, fitness, and international trade, since the US customary system (ounces, pounds, stones) and the metric system (grams, kilograms) are both widely used, often for the exact same real-world item described two different ways. The gram is one-thousandth of a kilogram, the SI base unit of mass. One ounce equals exactly 1/16 of a pound, or about 28.3495 grams.
Enter your value and confirm the "From Unit" dropdown is set to Grams -- the result grid updates instantly, showing your value converted into every unit in this weight category at once (not just Ounces), so you can see multiple equivalent measurements without switching tools. There's no button to press and nothing is sent to a server, so it works the same on a phone with no signal as it does on a desktop.
Ounces = Grams × 0.03527396
The pound is defined as exactly 0.45359237 kilograms by the same 1959 international agreement that fixed the inch -- this makes pound-to-kilogram conversions exact, and every other US customary weight unit (ounces, stones) derives from that same fixed pound definition.

This calculator carries full precision internally and only rounds the final displayed result for readability -- if you need more or fewer decimal places than shown, the underlying value is still exact to the limits of floating-point arithmetic.
Multiply the Grams value by 0.03527396 to get Ounces. This calculator does that automatically as you type, so you don't need to do the multiplication by hand.
Yes -- 1 Grams equals 0.03527396 Ounces by definition, so the result is mathematically exact rather than a rounded estimate (the displayed value may be rounded for readability, but the underlying calculation isn't).
Yes -- change the "From Unit" dropdown above the input to switch direction. The same conversion engine handles every unit in this category, not just Grams and Ounces.
Technically mass, though "weight" is the everyday term used for both -- Grams and Ounces here measure the same physical mass regardless of gravity, unlike a physics-specific "weight" (a force) which would vary depending on where it's measured.
Ounces is one of the standard units for measuring weight -- see the Practical Uses section above for the specific contexts where it's most commonly encountered.
