The formula
How to convert USD to AUD
A USD to AUD conversion is arithmetic, not guesswork — multiply and you are done. On 18 August 2026 that rate is 1.4055, so:
AUD = USD × 1.4055
Backwards works identically — divide by 1.4055, or multiply by 0.711468. One Australian Dollar comes to 0.711468 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 Australian Dollar
The US Dollar (USD, symbol $) is the currency of the United States. The Australian Dollar (AUD, symbol A$) is the currency of Australia.
The rate is set by continuous trading, which is why it rarely reads the same two days running. Everything on this page is a mid-market rate. Retail providers quote a spread around it and keep the difference.
Worked USD to AUD examples
A price tag. Something marked $50 comes to 70.2772 AUD. Round to 70 AUD for a quick mental check while you are standing in the shop.
A monthly salary. $3,000 a month is 4216.63 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 US Dollars, that is 711.47 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 681.69 AUD instead of 702.77 AUD. That gap is what the mid-market rate on this page lets you spot.
One US Dollar is worth 1.4055 Australian Dollars as of 18 August 2026. The rate comes from the daily reference feed and refreshes automatically every morning.

No — treat it as the reference point, not the offer. Exchange desks quote a spread around the mid-market rate and keep the difference. Comparing their quote with the figure above tells you what the convenience is costing you.
