Frequently Asked Questions

Why are cooking recipes using ounces when most countries use grams?

Ounces are common in older recipes and in countries using imperial measurements (US, UK). Many modern recipes now include both units for convenience.

Is 28 grams exactly 1 ounce?

Approximately - 1 ounce equals 28.3495 grams. For cooking purposes, rounding to 28 grams is usually acceptable unless extreme precision is needed.

What's the difference between avoirdupois ounces and troy ounces?

Avoirdupois ounces (used in cooking) = 28.35 grams. Troy ounces (used for precious metals) = 31.1 grams. This converter uses avoirdupois ounces.

Real-World Examples & Use Cases

International Cooking & Baking

European and most international recipes specify ingredient weights in grams for precision baking. American recipes and many traditional cookbooks use ounces. When following a French pastry recipe requiring 250 grams of butter (8.82 oz) or a German bread recipe with 350 grams of flour (12.35 oz), gram-to-ounce conversion lets American bakers measure accurately with their imperial kitchen scales. Precision matters especially in baking, where small weight discrepancies can affect dough texture, rise, and final product quality.

Retail Packaging & Nutrition Labels

Food products sold in the US must display weight in ounces on packaging, while metric-sourced products list grams. Converting between the two helps buyers compare unit prices across differently labeled products. A 200g pack of crackers equals 7.05 oz. Nutritionists comparing food databases, food manufacturers creating dual-unit packaging for international distribution, and retail importers adapting metric product labels for US markets all rely on precise gram-to-ounce conversion for accuracy.

Coffee, Tea & Specialty Food Retail

Specialty coffee and loose-leaf tea are often sold in gram quantities — standard espresso shots are 18-20 grams (0.63-0.71 oz) per double shot, and tea servings are measured in grams. American coffee shops and specialty retailers need to communicate these quantities in ounces for menus and packaging targeted at US customers. Baristas dialing in espresso recipes, tea merchants creating product descriptions, and food bloggers translating specialty ingredient quantities need gram-to-ounce conversion regularly.

Postal & Shipping Weight Documentation

Small packages, letters, and parcels are weighed in grams at international postal services but in ounces by USPS (United States Postal Service). A 100-gram package equals 3.53 oz. International senders shipping to the US, or US sellers calculating shipping costs for small items from metric weight scales, need accurate gram-to-ounce conversion to correctly complete customs documents, postage calculators, and carrier weight declarations.

How It Works

Gram to ounce conversion is straightforward when using the avoirdupois ounce (the standard ounce for everyday use). The conversion formula: Ounces = Grams ÷ 28.3495 The exact value: 1 ounce (avoirdupois) = 28.349523125 grams This can also be expressed as: Ounces = Grams × 0.035274 Important note on ounce types: - Avoirdupois ounce (this converter): 28.3495 g — used for food, parcels, everyday items - Troy ounce (precious metals): 31.1035 g — used for gold, silver, gemstones For cooking, always use avoirdupois ounces. When reading precious metals pricing, troy ounces apply. Key cooking reference weights: - 28.35 g = 1 oz - 113.4 g = 4 oz - 226.8 g = 8 oz - 453.6 g = 16 oz (1 pound)

Frequently Asked Questions

How many grams is 1 ounce?
1 ounce (avoirdupois) equals 28.3495 grams (sometimes rounded to 28 grams for cooking estimates). The exact international definition is 28.349523125 grams per ounce.
What is 100 grams in ounces?
100 grams equals 3.527 ounces (100 ÷ 28.3495 = 3.527). This corresponds to roughly a quarter pound. Chocolate bars and food portions are often 100g, making this a useful everyday reference.
What is 500 grams in ounces?
500 grams equals 17.637 ounces (500 ÷ 28.3495 = 17.637). A 500g package is just over 1 pound and 1.6 oz. Flour, sugar, and pasta are commonly sold in 500g packages internationally.
What's the difference between a fluid ounce and a weight ounce?
A fluid ounce (fl oz) is a volume measurement (29.57 mL). A weight ounce (oz) is a mass measurement (28.35 g). They are different units used for different purposes. Recipes specify fluid ounces for liquids and weight ounces for dry ingredients.
Can I use this converter for precious metals like gold?
No — precious metals use troy ounces (31.1 grams each), which are about 10% heavier than avoirdupois ounces (28.35 grams). To convert grams of gold to troy ounces, divide by 31.1035 instead. This converter uses avoirdupois ounces intended for food and everyday weight.
Is 28g the same as 1 oz?
28 grams is a common cooking approximation for 1 ounce, but the exact value is 28.3495 grams. For everyday cooking, 28g is close enough. For precision baking or scientific work, use the full 28.3495 factor.
