Philippine peso to Australian dollars, in your head
One rule, the error band that comes with it, and the point at which it stops being the right rule. Updated from the live rate feed.
Pesos to Australian dollars. Accurate to within 0.8% at today's rate, which means it reads about 0.8% cheaper than the real price — round up, not down.
The ladder
The middle column is what the rule gives you standing in a market. The right column is the real number, so you can see exactly where the shortcut costs you.

What catches people out in the Philippines
Small vendors and jeepney fares run on coins and small notes, so the useful mental range is 20 to 500 rather than the thousands.
When this rule stops working
Rules of thumb rot quietly. This one holds while the rate stays roughly between 42.5 and 43.5 PHP to the Australian dollar. Outside that band a different divisor becomes the better one to memorise. We regenerate this page from the live rate feed, so the date above tells you how fresh the number is — if you are reading this a long way after August 2026, check it before you rely on it.
