Australia has been fully metric since 1974, but inches still appear on TV screens, monitors, phone displays, and bike wheel sizes. A "55-inch TV" is 139.7 cm diagonal. Tyre sizes also list rim diameter in inches (e.g. 17-inch rims). Knowing how to convert helps when shopping for US-origin products or reading international tech specs.
