What catches people out in Malaysia
Ringgit sit close enough to a quarter of a US dollar that a rough "divide by 4" gets you inside 10% almost all the time.
When this rule stops working
Rules of thumb rot quietly. This one holds while the rate stays roughly between 4.95 and 5.05 MYR to the franc. 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.
