# Currency exchange rate (`exchange_rate`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Price of one currency expressed in another, as a decimal number, for example 97.8637 units of the local currency for one unit of the foreign currency. Customs declarations and invoices keep it next to the currency code and the amount in the foreign currency, to convert the amount to the local currency. The number alone does not say which currencies it relates or in which direction, so the field name is the evidence.
