The formula
How to convert USD to SGD
The maths behind a USD to SGD conversion is straightforward: one multiplication, no rounding tricks. On 11 August 2026 that rate is 1.2806, so:
SGD = USD × 1.2806
Going the other way, divide instead of multiply — or multiply by 0.780905, which is the same thing: one Singapore Dollar buys 0.780905 US Dollars.
The converter at the top of this page does both directions and updates as you type. Every result is recalculated on the server as well, so the number you see is the number that gets stored.
About the US Dollar and the Singapore Dollar
The US Dollar (USD, symbol $) is the currency of the United States. The Singapore Dollar (SGD, symbol S$) is the currency of Singapore.
Like any currency pair, the rate reflects what traders are willing to pay at that moment, not a fixed value. The figures here are mid-market reference rates pulled from a public daily feed; they are the rate you will see quoted in the news, not the rate a retail exchange will hand you over the counter.
Worked USD to SGD examples
A price tag. Something marked $50 comes to 64.0283 SGD. Round to 64 SGD for a quick mental check while you are standing in the shop.
A monthly salary. $3,000 a month is 3841.7 SGD — useful when you are comparing a job offer across the two markets. Bear in mind the rate moves, so a figure agreed today will not be the figure paid out in six months.
Going the other way. If you are holding S$1,000 and want to know what it buys in US Dollars, that is 780.91 USD. The converter handles both directions — use the swap button between the two fields.
Watch the margin. At a bureau charging 3%, your $500 would fetch roughly 621.07 SGD instead of 640.28 SGD. That gap is what the mid-market rate on this page lets you spot.

No. This is the mid-market reference rate — the midpoint between what buyers and sellers are quoting. Banks, card issuers and exchange bureaus add a margin on top, so expect to receive somewhat less than the figure shown here. Use it as a benchmark to judge whether an offer is fair.
