The short ton unit used in the United States is 1 percent of a short ton (20 lbs.). Tungsten xide is 79.3 percent tungsten by weight, therefore, a short ton unit of WO3 equals 20 pounds of WO3 and contains 7.19 kg (15.86 lbs.) of tungsten. The metric ton unit, which is used in most other countries, is 1 percent of a metric ton (10 kg).
