South Korea is used to represent the amount of relationships between relatives, such as 1 inch to indicate the relationship between the two -generation person. Waiting for the ancient system, 1 -inch = 3.33 cm. but this unit is almost unused in Hong Kong, but only "inch" (1 -inch = 2.54 cm) and "cm"; "inch" usually refers to "inches". Extension information:
