Why ounces and grams trip up bakers

American recipes lean on ounces and pounds, while most of the world (and nearly every good baking recipe) measures in grams and kilograms. When you find a cake or bread recipe from another country, the numbers rarely line up with your kitchen scale. This converter bridges the gap instantly: enter a weight in any unit and the other three update in real time, so you never have to keep a conversion chart taped to the cabinet.

The exact conversions used

This tool converts everything through grams as a common base, using these standard kitchen ratios: 1 ounce = 28.35 grams, 1 pound = 453.6 grams, and 1 kilogram = 1,000 grams. So 8 oz works out to about 226.8 g, and 2 lb is roughly 907.2 g. Results are rounded to four decimal places and trailing zeros are trimmed, which keeps everyday amounts clean and readable while staying precise enough for scaling recipes up or down.

How to use it

Press Clear to reset every box and start a new conversion.

FAQ

Are these fluid ounces or weight ounces?: Weight (dry) ounces. This is a mass converter for a kitchen scale, not a volume tool. One fluid ounce of water happens to weigh about one weight ounce, but flour, sugar, and butter do not — always weigh by mass for baking accuracy.
Why does grams read 28.35 for one ounce instead of 28.3495?: This tool uses 28.35 g per ounce, the rounded value common in cooking. It is more than accurate enough for recipes; the tiny difference never affects a batch of cookies.
Is my data uploaded anywhere?: No. Every calculation runs in your browser. Nothing you type is sent to a server or saved.
Can I convert pounds straight to kilograms?: Yes. Type a value in the pounds box and read the kilograms box — for example, 1 lb shows as about 0.4536 kg.
