Jin, pound and two are commonly used units of weight in Hong Kong. According to Hong Kong standards, one catty is equivalent to 600g, and one catty contains 16 liang, and one liang equals 37.5g.. The use of such units is quite common in the local area, but there may be different weight units and conversion ratios in other regions and cultures. Therefore, it is very important to know the local weight unit and the corresponding conversion relationship when conducting cross-cultural exchanges and transactions, so as to avoid misunderstanding and confusion.
