Pound sterling to dirhams, 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.

THE RULE
multiply by 4.9

Pounds to dirhams. Accurate to within 0.7% at today's rate, which means it reads about 0.7% 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 UK

Sterling is the one major currency where the number on the tag is smaller than the dollar amount you will actually pay. Round up, not down.

When this rule stops working

Rules of thumb rot quietly. This one holds while the rate stays roughly between 0.392 and GBP to the dirham. 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.
