A ton is a unit of weight and mass used in the United States. It is related to other units, such as ounces and pounds. If you know how many ounces or pounds an object weighs, you can calculate the number of tons it weighs.

## Calculating Tons From Pounds

One ton is equal to 2,000 pounds. Use this ratio between the two units as a conversion factor to calculate tons from pounds. Consider a boulder that weighs 9,000 pounds. Calculate the number of tons as follows:

9,000 pounds x (1 ton / 2,000 pounds) = 4.5 tons

## Calculating Tons From Ounces

One ton is equal to 32,000 ounces. Again, use this ratio as a conversion factor to calculate tons from ounces. Consider a toaster that weighs 64 ounces. Calculate the number of tons as follows:

64 ounces x (1 ton / 32,000 ounces) = 0.002 tons
