Frequently asked questions
0.035274 ounces, since the avoirdupois ounce is 28.349523125 grams — one sixteenth of a pound. Divide grams by 28.3495 to get ounces.
An ounce measures mass; a fluid ounce measures volume. They are only numerically similar for water, by coincidence. Worse, there are two fluid ounces — the US at 29.574 ml and the imperial at 28.413 ml. Converting 8 fluid ounces of flour as though it were 8 ounces of weight gives a badly wrong quantity, because flour is far less dense than water.
Divide the price per troy ounce by 31.1035 to get a per-gram figure, then apply the exchange rate, then add import duty and GST. That last step is why the Indian retail price sits meaningfully above a naive conversion. Using the ordinary 28.35 g ounce instead of the troy ounce overstates the per-gram price by about 10%.
One gram is 0.035274 ounces
A gram converts to 0.03527396 ounces, because the avoirdupois ounce is 28.349523125 grams — one sixteenth of a pound.
Ounces = grams ÷ 28.3495
Where this matters
Cooking from foreign recipes is the main one. American recipes frequently specify dry ingredients by weight in ounces, and the conversion is needed before an Indian kitchen scale is any use:
- 1 oz = 28.35 g
- 4 oz = 113.4 g
- 8 oz = 226.8 g
- 16 oz = 453.6 g (1 lb)
Postal and courier rates, where international services sometimes band by ounce.
Precious metals, which use a different ounce entirely — see below.
Food packaging from imported goods, where the net weight may be in ounces.
The troy ounce, and why it matters for gold
This is the distinction most worth carrying away, because it affects money.
Avoirdupois ounce — the ordinary one, 28.3495 g, used for food, post and general weight. Sixteen to a pound.
Troy ounce — used for gold, silver, platinum and other precious metals, 31.1035 g. Twelve troy ounces make a troy pound.
The troy ounce is about 10% heavier. International gold prices are quoted per troy ounce; Indian gold is sold per gram or per 10 grams. Converting an international quotation using the wrong ounce overstates or understates the price by roughly a tenth, which on any meaningful quantity is a large error.
To convert an international gold price to an Indian per-gram figure: divide the price per troy ounce by 31.1035, then apply the exchange rate, then add import duty and GST — which is why the domestic price is meaningfully above the naive conversion.
The tola, still used in Indian jewellery, is 11.6638 grams — about 0.375 troy ounces.
Fluid ounces are a volume, not a weight
A separate and frequent confusion. A fluid ounce measures volume, not mass, and the two are only numerically similar for water by coincidence.
Worse, there are two fluid ounces: the US fluid ounce at 29.574 ml and the imperial fluid ounce at 28.413 ml. A recipe calling for "8 fl oz" means about 237 ml in American usage and 284 ml in British.
Converting 8 fluid ounces of flour as though it were 8 ounces of weight produces a badly wrong quantity, because flour is far less dense than water. For baking in particular, weight is the reliable measure and volume is not.
