To sort out these terms, you don't measure a fabrics thickness, it is about the weight per square yard (1 yard = 0.9144 meters). You weigh the unwashed fabric and the weight is calculated in ounces where 1 ounce = 28.3 grams. To simplify this, one can say that an unwashed 501 from the 50s weighs about 12oz, which means these jeans from Pike Brothers is almost twice as thick as any other unwashed jeans. They can stand by themselves and is certainly something you will wear for a long time to come.
