How to Measure 15 oz Without a Scale

No scale handy? These simple tricks help you get close to 15 oz, in weight or volume, using things you already have.

Use a Standard Can

A can is a ready-made 15-ounce weight. Many cans of beans, soup, and vegetables are labeled 15 ounces. Just grab one from the pantry and hold it to feel the weight, or use it on a balance to weigh an equal amount of something else. Because the weight is printed on the label, this is one of the most accurate no-scale references. Most kitchens have a 15-ounce can on hand, making it an easy guide.

Use Measuring Cups for Liquids

Measuring cups handle 15 fluid ounces easily. Since a cup holds 8 fluid ounces, fill a two-cup measure to just below the top, at the 15-ounce line if marked, or an ounce short of 2 cups. This works for water, milk, and other liquids. Most kitchens have measuring cups, making this a quick and close method for gauging 15 fluid ounces without any special tools.

Count Coins for Weight

Nickels make a handy little scale. Since each US nickel weighs exactly 5 grams, 85 of them come to about 425 grams, or 15 ounces. Count out the nickels and hold them, or place them on one side of a balance to weigh an equal amount. Because coins have known, exact weights, this is a reliable no-scale method, though counting 85 takes a moment. It works well when you need a precise reference.

How 15 oz Compares to Other Common Amounts

Seeing 15 oz next to nearby amounts helps it click. 8 oz is about half, close to a cup of water or a small can. 15 oz is our target, a standard can of beans. 16 oz is one pound, just an ounce more, like a full pint. And 32 oz is two pounds, about a large bottle of soda. So 15 oz is a moderate weight, just under a pound, common for canned foods.

Amount	Compared to 15 oz	Everyday Example
8 oz	About half	A cup of water
15 oz	The base amount	A can of beans
16 oz (1 lb)	An ounce more	A full pint
32 oz (2 lb)	Over double	A large soda bottle
