Suppose you pick up a bedsheet package that quotes 200 Threadcount per square inch (2.54cm x 2.54cm). Let's say that is made up of 100 threads along the length of 2.54cm, plus 100 threads along the width of 2.54cm. Since 10 square centimetres is 3.16cm x 3.16cm, this equates to 124 threads along the 3.16cm length, plus 124 threads along the 3.16cm width. Threadcount per 10 sq cm is therefore 124+124, which rounds up to 250.
Combining these technologies, we were able to read and write data in our laboratory system at a linear density of 818 000/in. For historical reasons, tape engineers around the world measure data density in inches. In combination with the 246 200 tracks per inch that the new technology can handle, our prototype unit achieved an area density of 201 gigabits per square inch.
All commercial engagements are to use the metric units.
In 1971, the National Bureau of Standards (NBS, now NIST) published the combined reports of the U.S. Metric Study, which also contained a map depicting a list of countries "uncommitted" to mandatory metrication (Figure 2). The U.S. and other countries listed were described as "Islands in a Metric World." The flaw with this perspective was that the concept didn't recognize that the U.S. had been "metric" since 1866, when the metric system was first legalized. A few years after the U.S. Metric Study was published, Congress passed the Metric Conversion Act adopting voluntary metrication that was signed into law by President Ford in 1975. Over time, various versions of the map/country list became integrated into even more metrication publications. The Central Intelligence Agency (CIA) Factbook is one of the often cited sources of the U.S./Liberia/Burma metric myth. The first unclassified version of the CIA Factbook was published around the same time the U.S. Metric Study. It's likely that the original list of "uncommitted" countries was incorporated, then edited as countries adopted mandatory metric laws. Over the years, many web resources have quoted the CIA Factbook, perpetuating the metric myth and elevating the map to a pop culture meme. The U.S. metrication status is best described as a Metric Continuum.

A survey from the British Weights and Measures Association, admittedly a partial source, suggested that 80 per cent of people prefer imperial to metric and 70 per cent, including, remarkably, 18- to 24-year-olds, can make sense of weights only in imperial measurements.
