We can measure the weight of something in ounces, pounds, and tons. The ounces we use here are different from the ounces used to measure volume. The terms just happen to be the same, which can be a bit confusing.
16 ounces = 1 pound 2000 pounds = 1 ton
ounces | pounds ----------|--------- 16 | 1 32 | 2 48 | 3 64 | 4 |
