About 日米単位変換

Japan-US Unit Conversion makes it easy to convert between the units used in Japan and those used in the US. It's handy for travel, daily life, work, and study.

  • 8 categories — Convert length, speed, weight, temperature, area, volume, currency, and time zones.
  • Dollar-yen conversion — Uses the latest exchange rate, and falls back to the last rate it fetched when you're offline.
  • Favorites — Save the conversions you use often so you can pull them up right away.
  • Copy and share — Copy a result or share it to another app.

FAQ:

  • What does the Premium Version include? — It removes in-app ads, lets you save unlimited favorites, and unlocks the exchange rate history chart (30 days, 90 days, 1 year) on the currency screen. In the free version, you can save one favorite per category.
  • How do I buy the Premium Version? — Tap the gear button at the top right of the home screen to open settings, then tap "Purchase Premium Version". It's a single purchase.
  • How do I get my purchase back on a new device or after reinstalling? — Sign in with the same Apple Account you purchased with, then tap "Restore Purchases" at the bottom of the settings screen.
  • Can I convert currency offline? — Yes. When you're offline, the app uses the last exchange rate it fetched and shows "(Offline)". If no rate has been fetched yet, currency can't be converted.
