How it's calculated

From BND to SGD: divide the amount by 1. From SGD to BND: multiply by 1. Because the rate is 1, the number stays the same.
The par rate is set by the agreement between Brunei Darussalam and Singapore. Banks in both countries accept the other country's notes for deposit.
What can change is the fee. A bank, a card network or a money changer may charge to convert, and a shop does not have to accept the other currency.

An example

BND 1,000 is SGD 1,000.00, and SGD 250 is BND 250.00. To turn either currency into US dollars you need the market rate for the Singapore dollar, because the Brunei dollar follows it.
