# Currencies

- Page: https://longbook.app/help/currencies/

Every commitment keeps its own currency, and each currency is totalled on its own. longbook never converts one into another.

## Set a currency

The commitment form has a currency beside the amount. INR, USD, EUR and GBP are on the quick selector, and the **Currency** list adds any other, searchable by code or name.

## Totals

- The dashboard totals one currency and lists the others beside it. A menu at the top switches between them.
- **Commitments** and **All charges** can be filtered by currency.
- A monthly report totals one currency and lists every charge in its own.
- Your AI gets totals per currency, never converted.

## Home currency

In **Settings**, under **Display & currency**, **Home currency** sets which currency the dashboard leads with. **Automatic** leads with the one most recurring commitments use. The choice appears once your recurring commitments use more than one currency.

## Questions

### Does longbook convert currencies?

No. longbook holds no exchange rates, so a total never moves with the market.

### Which currencies can I use?

Any currency in current use, by its three-letter code.

### What currency does Siri use?

An amount said in rupees, dollars, pounds, euros, dirhams or yen keeps that currency. Any other amount takes the currency most of your commitments use.

Still have a question? Open **Support** in the app, under **Settings**, then **Help & about**, or write to contact@longbook.app and a person answers.
