Tsubomoto

Tsubomoto helps you convert tatami, tsubo, and square meters, and estimate DIY materials offline — paint cans, wallpaper rolls, and tile counts in shopping units. Four modes: • Area — switch among tsubo, m2, and tatami standards • Paint — liters to can counts; optional two-part mix ratios • Wallpaper — rolls from width, length, and trim • Tile — counts with grout (not a simple area / tile area) Works offline. History stays on device. An optional one-time unlock raises the history limit. Results are estimates. Always check product labels and manufacturer specs before buying or installing.
