About

Global trade and international recipes often hit a friction point at the border between Metric and Imperial systems. This tool converts Grams (g) to Avoirdupois Ounces (oz), the standard unit of weight used in the United States and UK for groceries, postal shipping, and general merchandise. It is crucial to distinguish this from "Fluid Ounces" (volume) or "Troy Ounces" (precious metals). This utility provides immediate, context-aware conversions with adjustable decimal precision to suit both rough kitchen estimates and precise shipping manifests.

Formulas

The standard Avoirdupois ounce is legally defined relative to the kilogram. The precise conversion factor is:

1 oz ≡ 28.349523125 g

To convert grams to ounces, divide by this factor or multiply by its reciprocal:

w_oz ≈ w_g × 0.035274

Frequently Asked Questions

Ounces (oz) measure weight/mass. Fluid Ounces (fl oz) measure volume. 1 fl oz of water weighs roughly 1 oz, but 1 fl oz of honey weighs about 1.5 oz. This tool calculates weight only.

No. Precious metals are weighed in "Troy Ounces". A Troy ounce (31.1g) is heavier than the standard Avoirdupois ounce (28.35g) used here.

For cooking, 1 decimal (e.g., 4.5 oz) is sufficient. For postage or shipping chemicals, 3 or 4 decimals are recommended to avoid overpayment or rejection.

100 grams is approximately 3.53 ounces. This is a common size for chocolate bars or spice packets.
