## Assumptions

- The default rate, 1 USD = 6.56987 DKK, is worked out by this site from the ECB euro reference rates of 28 September 2026: 7.4752 DKK per euro ÷ 1.1378 USD per euro, rounded to 6 significant figures. The ECB does not publish rates between two non-euro currencies.
- The ECB publishes its reference rates for information purposes only, not for transactions. Banks and cards add a margin or a fee; type their rate to see what you would get.
- Amounts are rounded to 2 decimal places, without trailing zeros (24.4 means 24.40), and rates show up to 7 significant figures; the calculation keeps full precision.
