square lm

Square Lm

㏐ means luminous flux measured in lumens. It is a fixed-cell form from legacy East Asian typography; the square changes layout, not the unit, and plain lm is clearer in new technical prose.

What ㏐ means

It denotes luminous flux measured in lumens. The square fits lm into a text cell sized like a Chinese, Japanese, or Korean character.

It belongs to a legacy East Asian convention that placed Latin unit abbreviations in the text cell used for Chinese, Japanese, or Korean characters.

㏐ and lm name the same unit. ㏓ packages lx (lux), which measures illuminance—the light reaching a surface—not luminous flux.

Specialist and legacy-typographic; plain lm is clearer in new technical prose.

The square changes layout, not the unit.

Why does ㏐ show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
