Created attachment 191248 [details] Mixture of IEC and SI units STEPS TO REPRODUCE 1. System Settings > Region & Language > Data and Storage Sizes > Metric System (SI) > Click "Apply" 2. Restart the system or plasmashell for good measure 3. Plug in a disk > mount it 4. Open the Disks & Devices popup again OBSERVED RESULT Main label is always expressed using IEC units; secondary label respects the value of BinaryUnitDialect and uses SI units EXPECTED RESULT Both labels use SI units SOFTWARE/OS VERSIONS Operating System: KDE Linux 2026-03-30 KDE Plasma Version: 6.6.80 KDE Frameworks Version: 6.25.0 Qt Version: 6.11.0 Kernel Version: 6.19.9-zen1-1-zen (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 7840U w/ Radeon™ 780M Graphics Memory: 17 GB of RAM (16.0 GB usable) Graphics Processor: AMD Radeon 780M Graphics

Git commit 0a48f09d4b2b2c69180b43ac769bc15205013d32 by Nate Graham, on behalf of Tobias Fella. Committed on 04/06/2026 at 18:42. Pushed by ngraham into branch 'master'. Use globally-configured storage size units for labeling disks Unfortunately this involves copying code from KCoreAddons, since Solid is tier 1 so we can't depend on it.
