Where 61,000 fits
Why 61,000 is special
It sets both how much interference a device may emit and how much it must tolerate, which is why a phone next to a speaker is a design failure rather than an inevitability.

6 × 10,000 + 1 × 1,000 = 61,000. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
