New "File Size Converter" widget (Math category): convert a size across every unit at once, rather than picking a from/to pair like the Unit Converter's Data category already does. Shows bits, the decimal system (Bytes, KB, MB, GB, TB, PB — powers of 1000), and the binary system (KiB, MiB, GiB, TiB, PiB — powers of 1024) simultaneously, so the gap between the two (a "1 GB" file reading as ~931 MiB) is visible without switching units back and forth. Each row has its own copy button. Pure conversion logic lives in fileSizeConversions.ts (unit tables, byte-based conversion, tolerant number parsing) with its own test file; the widget and its tests follow the existing NumberBaseConverterWidget layout pattern (persistent value/unit via useWidgetState, one row per unit, ErrorMessage for invalid input).

Correct the widget count.
The category table lists 35 widgets, but this line says 34 tools. Update the count to 35 so the summary matches the listed widgets.

Reject malformed comma grouping.
parseSize documents commas as thousands separators, so 1,2 and 1,,000 are invalid inputs. The current replacement converts them to 12 and 1000, which makes FileSizeConverterWidget render conversions instead of Enter a number.
Validate comma placement before removing commas, and add malformed-grouping tests.
Proposed fix
if (trimmed === '') return null
+ if (trimmed.includes(',') && !/^[+-]?(?:\d{1,3}(?:,\d{3})+)(?:\.\d+)?(?:e[+-]?\d+)?$/i.test(trimmed)) {
+ return null
+ }
const withoutCommas = trimmed.replace(/,/g, '')📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

What
New File Size Converter widget (Math category): type a size and see it converted into every storage unit at once, rather than picking one "from" and one "to" unit at a time.
Preview: https://claude.ai/artifact/S7UNomwzHBqFkKZmKgQZ57 (a build of this branch, opening on the new widget)
Why a dedicated widget
The Unit Converter's "Data" category already covers Bytes → GiB, but as a from/to pair. This widget shows every unit simultaneously (Bit, Bytes, KB…PB, KiB…PiB), which is the more useful shape for the actual question people have: "how big is this file in every unit I might care about" — and it makes the decimal/binary gap visible without switching units back and forth. It defaults to 1 GB, which reads as ~931 MiB / ~0.93 GiB, right on open — that gap (a "1 TB" drive showing as "931 GiB" in a file manager) is the single most common source of file-size confusion, so the widget shows both systems side by side instead of making the user pick one.
Structure
fileSizeConversions.ts— pure module: unit tables for the three systems (bit, decimal/powers-of-1000, binary/powers-of-1024),toBytes/fromBytesconversion through the byte base unit, and a tolerantparseSize(handles+/-, thousands commas, blank vs. invalid). Own test file, 13 tests.FileSizeConverterWidget.tsx— one size/unit input row, three grouped result lists (Bit / Decimal / Binary), each row copyable. Follows the existingNumberBaseConverterWidgetlayout pattern (label + value + copy button per row) anduseWidgetStatefor persistence. 8 tests, including a remount-persistence test and the decimal/binary gap itself as a regression check.registry.ts, README widget table and count updated.Testing
npx tsc -b --noEmit,npm run lint(only the two pre-existingPageColorPicker.tsxwarnings),npm test: 958 passing, 21 of them new.npm run buildsucceeds; the widget lands in its own lazy chunk.🤖 Generated with Claude Code
