Colombian 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 0.1% at today's rate, which means it reads about 0.1% 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 Colombia
Colombian prices routinely run to six figures, and locals often drop the thousands when speaking — "veinte" for a 20,000 peso item.
When this rule stops working
Rules of thumb rot quietly. This one holds while the rate stays roughly between 3,850 and 3,950 COP 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.
