Editing Gigabyte (section)

===US lawsuits===
A lawsuit decided in 2019 that arose from alleged breach of contract and other claims over the binary and decimal definitions used for "gigabyte" have ended in favour of the manufacturers, with courts holding that the legal definition of gigabyte or GB is 1&nbsp;GB = 1,000,000,000 (10<sup>9</sup>) bytes (the decimal definition). Specifically, the courts held that "the U.S. Congress has deemed the decimal definition of gigabyte to be the 'preferred' one for the purposes of 'U.S. trade and commerce' .... The California Legislature has likewise adopted the decimal system for all 'transactions in this state'."<ref name="Order Granting Motion to Dismiss"/>

Earlier lawsuits had ended in settlement with no court ruling on the question, such as a lawsuit against drive manufacturer [[Western Digital]].<ref name="WesternDigital">{{cite web
