- Divide by 40.3399 for euros, or multiply by 40.3399 for BEF. The calculator keeps the full fixed rate and rounds only the displayed amount.

Does this show what an old price is worth today?
No. It converts the currency denomination at the official fixed rate. Inflation adjustment is a separate calculation requiring the country and both comparison years.
Can I still exchange old banknotes or coins?
A numerical conversion does not establish whether cash can still be redeemed. Check the relevant national central bank’s rules for the specific currency and cash type.
Can I use a decimal comma?
Yes. Numeric fields accept 12.5 or 12,5 and spaces for thousands, such as 1 234.50. Do not mix a point and comma in one number.
