What ㎧ means
It means meters per second.
It represents the same speed unit as m/s; the square shape is typographic and adds no scientific meaning.
The compact form belongs to an older family of square Latin unit abbreviations, made for East Asian character grids so a unit could occupy one full-width cell. The larger group draws on Japanese and Korean character standards; related signs include for meters per second squared and for cubic meters.
How do I enter ㎧?
Use Unicode input for the exact sign; use m/s for ordinary notation.
An editor with Unicode code-point entry can insert U33A7; the keystrokes depend on the app. NFKC and NFKD apply its compatibility mapping, unfolding it into ms, where is the Unicode division slash. That can change exact-character searches, equality checks, or round-tripping of the compact form.
Technical and legacy typographic; the square form fits a fixed-width CJK-style cell, while m/s is clearer in ordinary notation.
Normalization can unfold the one-cell form into ms.
Drift: Japanese school textbooks shifted from m/秒 to m/s around 2012 to follow SI notation; the unit stayed the same.
Don't confuse it with
1m/s The same meters-per-second unit in ordinary SI spelling; it is readable notation, not the compact one-cell character.
Questions people ask
2Will normalization preserve ㎧ as one glyph?
No. NFKC and NFKD can expand it through its compatibility mapping into ms, so text processing may lose the compact form.
Why is ㎧ square?
The shape lets the abbreviation occupy one full-width character cell in East Asian text; it does not change the unit.
