Chilean peso to Swiss francs, 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 Swiss francs. Accurate to within 4.3% at today's rate, which means it reads about 4.3% 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 Chile
Chilean prices are whole numbers in the thousands, and the peso has no practical subunit, so the arithmetic is simpler than the size of the numbers suggests.
When this rule stops working
Rules of thumb rot quietly. This one holds while the rate stays roughly between 1,150 and 1,250 CLP 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.
