When You Need Weight Conversions in the Kitchen
The most common situation is following a recipe from a different country. US recipes often use pounds and ounces, while UK, Australian, and European recipes use grams and kilograms. Meat and produce labels at the grocery store are often in pounds, while cooking guides may give quantities in grams. This converter bridges all of those.
Weight conversions are also useful when scaling recipes. If a recipe calls for 8oz of chicken and you have a kitchen scale set to grams, knowing that 8oz = 227g saves you from doing mental math mid-cook.
Common Weight Conversion Reference
| Oz | Grams | Pounds |
|---|---|---|
| 1 oz | 28g | 0.063 lb |
| 2 oz | 57g | 0.125 lb |
| 4 oz | 113g | 0.25 lb |
| 8 oz | 227g | 0.5 lb |
| 12 oz | 340g | 0.75 lb |
| 16 oz | 454g | 1 lb |
| 32 oz | 907g | 2 lb |
Why Weighing Beats Measuring Cups
For baking especially, weight is more accurate than volume. A cup of flour can weigh anywhere from 120g to 160g depending on how it's scooped, how settled it is in the bag, and the humidity. A cup of brown sugar packed tightly weighs more than one loosely filled. When a recipe gives gram weights, use them — the results are more consistent every time.

Frequently Asked Questions
How many grams in an ounce?
There are 28.35 grams in 1 ounce. For quick mental math: 1 oz ≈ 28g, 4 oz ≈ 113g, 8 oz (half pound) ≈ 227g, 16 oz (1 pound) ≈ 454g.
How many ounces in a pound?
1 pound = 16 ounces = 453.6 grams. This is one of the most useful cooking conversions to memorize, since US recipes often switch between the two units for meat and produce.
How many grams in a pound?
There are 453.6 grams in 1 pound, typically rounded to 454g in cooking. Half a pound is 227g; a quarter pound is 113g. Most useful when buying meat listed in pounds and a recipe specifies grams.
How do I convert kilograms to pounds?
Multiply kilograms by 2.205 to get pounds. For a quick estimate, multiply by 2.2. So 1kg ≈ 2.2 lbs, 2kg ≈ 4.4 lbs, 0.5kg ≈ 1.1 lbs. To go from pounds to kilograms, divide by 2.205.
Is this converter for dry or liquid ingredients?
This converter handles weight only — grams, ounces, pounds, and kilograms apply to any physical substance regardless of whether it's dry or liquid. For liquid volume conversions (cups, milliliters, fluid ounces), use the Liquid Converter. For ingredient-specific weights like cups of flour or sugar, use the Cups to Grams Calculator.
Meat and Protein Portion Sizes by Weight
Grocery meat labels are almost always in pounds or ounces, but many nutrition and recipe guides think in grams. A standard single protein portion is 4-6 oz (113-170g) of meat, fish, or poultry per person — useful to know when scaling a recipe up or down for a specific number of servings.
| Serving Size | Oz | Grams |
|---|---|---|
| Small portion | 4 oz | 113g |
| Standard portion | 6 oz | 170g |
| Large portion | 8 oz | 227g |
Why do US recipes use ounces and pounds while others use grams?
It comes down to which measurement system a country adopted. The US never fully switched to the metric system, so pounds and ounces remain standard in American recipes and grocery labeling. Most of the rest of the world uses the metric system (grams, kilograms), which is part of why converting between the two is such a common need for anyone cooking from international recipes.
How accurate do I need to be when converting weight for cooking?
For most cooking, rounding to the nearest gram or ounce is more than accurate enough — a few grams of difference in a pound of meat or a cup of flour won't noticeably change a dish. Precision matters more in baking, where ratios between ingredients (especially leavening agents) are more sensitive to small changes.
Buying Meat by Weight: Price Per Pound vs Price Per Kilogram
When comparing prices between US and international grocery listings, remember that a price per kilogram needs to be divided by roughly 2.2 to compare fairly against a US price per pound — otherwise the kilogram price looks misleadingly higher for the same actual cost per unit of meat. This comes up often when comparing recipe costs or grocery prices across countries that use different weight-based pricing conventions.
