Dotori Unit Converter
Choose a category and type into any row. The other rows update together, so you can compare several units on one screen. Every conversion works offline, including on first use.
What it does
Eight categories
Length, area, volume, weight, temperature, speed, time and data size. Metric, customary and Korean traditional measures appear alongside each other where available. Decimal and binary data units are shown separately.
Every row is an input
Enter a value in any row to use it as the source. The other rows follow immediately, and the source row keeps the unit you chose.
Units that fit the value
Turn on automatic unit selection to choose a readable scale for the other eligible rows. A distance of 10 ri can appear in kilometres instead of a long number of centimetres.
Keep a unit fixed
Choose a unit manually to lock that row, or return the row to automatic selection. Temperature and time use fixed comparison rows.
Korean measures, clearly labelled
Compare pyeong, don, geun, doe, ja and ri. They appear by default when the app language is Korean or the device region is Korea. Settings offer automatic display, always show and hide. Geun is labelled separately as 600 g for meat and medicinal herbs, and 375 g for vegetables and fruit; automatic selection never switches between them.
Offline from the first conversion
No account, login or conversion-table download is needed. Use the built-in keypad to enter numbers and compare results directly. Online advertising and privacy-choice management can require a connection.

Known limits
Korean traditional measures use the conversion definitions shown in the app. Local market practices may differ; choose the labelled geun definition that matches your purpose.
Automatic unit selection applies only to eligible rows and units. The row being edited stays in its chosen unit; temperature and time remain fixed.
Privacy
Conversion runs on your device. The app does not send conversion numbers, results or selected units to the developer or the advertising SDK. One banner uses Google Mobile Ads, with privacy choices managed through Google UMP; there are no interstitial ads. Stored preferences may be included in Android backup or device transfer. See the full policy for advertising data, local storage and backup details.
