What 瓸 means
It marks a 100-gram measure in Japanese notation. A metrology study lists 瓸 among 22 compact unit characters in weather reports from July 1891; it leaves the creation date unsettled.
These signs shorten metric units: 瓦 is the gram element, while 瓧 and 瓩 mark other scales. Chinese dictionaries give the Mandarin reading bǎiwǎ, in pinyin (Chinese sound spelling), roughly “bye-wah” with low-rising tones, for an older written unit of 100 watts.
Technical; suited to unit notes or historical transcriptions.
Check the language before conversion: Chinese dictionaries also record 100 watts.
