 Customary Units for Measuring Weight Ounces Pound Ton

We can convert the customary unit of weight by using the giving relations.

Example: How many ounces are there in 1 ton?

1 ton = 2000 pounds

1 pound = 16 ounces

So, 2000 pounds = 2000 × 16 = 32000 ounces

 Customary Unit Customary Equivalent Standard Metric Equivalent 1 ounce -- 28.349523125 grams 1 pound 16 ounces 453.59237 grams 1 ton 2000 pounds 907.18474 kilograms

### Customary Units for Capacity (Volume)

Example: Convert 3 quarts to cups.

1 quart = 2 pints

2 quarts = 6 pints

1 pint = 6 cups

6 pints = 6 × 6 = 12 cups
