GlobalCalc: Currency Converter

Convert three currencies at the same time.

GlobalCalc is a currency converter for international travel, overseas shopping and everyday exchange-rate checks. Enter an amount in any of three currencies and the other two values update together.

76 currencies

Choose from 76 currencies, including USD, EUR, GBP, JPY, CNY, HKD, KRW, SGD, AUD, CAD and many more. Search by currency name or code to quickly build the comparison you need.

Three-way currency conversion

Compare your home currency, destination currency and a reference currency on one screen. Tap any row, enter an amount and see the other two conversions immediately.

Updated rates with offline fallback

Refresh exchange rates when needed and check the displayed update time. If the network is unavailable, GlobalCalc falls back to the most recently saved rates so you can keep converting on the go.

Useful for travel and shopping

Compare prices abroad, estimate card spending, check hotel and transport costs, or calculate cross-border purchases without converting each currency separately.

Calculator when you need more

Use standard and scientific modes for arithmetic, percentages, parentheses, trigonometric functions, logarithms, powers, roots and mathematical constants.

Floating calculator

Open a compact calculator above other apps while you browse, chat or compare prices. Floating mode requires Android's “Display over other apps” permission.

More conversion tools

Convert length, area, volume, weight, temperature, speed, pressure, power and number bases from the same app.

Calculation history

Review previous expressions and results, then reuse them without entering everything again.

No account required.

Check exchange rates, compare three currencies and handle everyday calculations with GlobalCalc.
