The formula
How to convert SGD to AUD
The maths behind a SGD to AUD conversion is one multiplication, no rounding tricks. On 15 September 2026 that rate is 1.1028, so:
AUD = SGD × 1.1028
To go from AUD back to SGD, divide by the same rate. Put another way, 0.906755 Singapore Dollars to the Australian Dollar.
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 Singapore Dollar and the Australian Dollar
The Singapore Dollar (SGD, symbol S$) is the currency of Singapore. The Australian Dollar (AUD, symbol A$) is the currency of Australia.
Neither currency is pegged to the other, so the figure drifts from one session to the next. Everything on this page is a mid-market rate. Retail providers quote a spread around it and keep the difference.
Worked SGD to AUD examples
A price tag. Something marked S$50 comes to 55.1417 AUD. Round to 55 AUD for a quick mental check while you are standing in the shop.
A monthly salary. S$3,000 a month is 3308.5 AUD — 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 A$1,000 and want to know what it buys in Singapore Dollars, that is 906.75 SGD. The converter handles both directions — use the swap button between the two fields.
Watch the margin. At a bureau charging 3%, your S$500 would fetch roughly 534.87 AUD instead of 551.42 AUD. That gap is what the mid-market rate on this page lets you spot.

Almost certainly not. What you see here is the mid-market rate, the midpoint of the market. Every retail provider takes a cut on top of it. The value of knowing the mid-market figure is being able to measure that cut.
