Frequently asked questions
QWhich box do I type in?
Either one. Typing on the left updates the right, and typing on the right updates the left, so it works whichever direction you came from.
QWhy do Korean traditional units differ from what I know?
Units like geun, doe and majigi vary by region and product — a geun of meat is 600 g but a geun of vegetables is 375 g. Each page notes where the value splits.
QAre these numbers exact?
Defined values such as 1 inch = 2.54 cm are exact. Values that depend on conditions, like Mach or traditional units, list the assumption on the page.
QWhy does my drive show less capacity?
This site uses 1 GB = 1,024 MB (binary). Drive makers count 1 GB as 1,000 MB, which is why a 1 TB SSD appears as 931 GB.
Traditional units (geun, doe, majigi and so on) vary by region and product.
