The formula
How to convert USD to SGD
The maths behind a USD to SGD conversion is one multiplication, no rounding tricks. On 14 September 2026 that rate is 1.2678, so:
SGD = USD × 1.2678
Reverse the direction and you divide rather than multiply. Equivalently, one Singapore Dollar is worth 0.788738 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 pair, the rate reflects what traders will pay at that moment, not a fixed value. What you see is the market midpoint, updated once a day. A bank or bureau will quote something a little worse.
Worked USD to SGD examples
A price tag. Something marked $50 comes to 63.3924 SGD. Round to 63 SGD for a quick mental check while you are standing in the shop.
A monthly salary. $3,000 a month is 3803.54 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 788.74 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 614.91 SGD instead of 633.92 SGD. That gap is what the mid-market rate on this page lets you spot.
Today's reading is 1.2678 SGD per US Dollar, recorded 14 September 2026. The daily feed updates it each morning without any action on your part.
That works out at 126.7848 SGD for 100 USD. Type a different figure into the converter to see it change as you go.
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.
