What 瓲 means
One metric tonne.
Japan's Central Meteorological Observatory notified weather stations about a compact metric-unit character set in 1891. 瓲 is a Japanese-made member: 瓦 marks gram; 屯 supplies the Japanese reading トン.
A 2011 account records it on a Tokyo Monorail weight notice, a preserved car, and machine-industry paperwork shifting toward t. Taiwan's 2024 Ministry of Education dictionary lists it as a Japanese special-use character.
Technical Japanese measurement notation with a legacy feel.
For older sources, check the standard: 噸 may refer to a non-metric ton.

1Why does 瓲 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.
