The formula
How to convert SGD to USD
There is only one number you need to convert SGD to USD: the rate the market is quoting. On 18 August 2026 that rate is 0.783117, so:
USD = SGD × 0.783117
Backwards works identically — divide by 0.783117, or multiply by 1.2769. One US Dollar comes to 1.2769 Singapore 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 Singapore Dollar and the US Dollar
The Singapore Dollar (SGD, symbol S$) is the currency of Singapore. The US Dollar (USD, symbol $) is the currency of the United States.
The rate is set by continuous trading, which is why it rarely reads the same two days running. What you see is the market midpoint, updated once a day. A bank or bureau will quote something a little worse.

A price tag. Something marked S$50 comes to 39.1558 USD. Round to 39 USD for a quick mental check while you are standing in the shop.
A monthly salary. S$3,000 a month is 2349.35 USD — 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 $1,000 and want to know what it buys in Singapore Dollars, that is 1276.95 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 379.81 USD instead of 391.56 USD. 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 bureaus add a margin, so expect somewhat less than shown. Use it as a benchmark to judge whether an offer is fair.
