\u010c\u00edslo re\u0165aze ANSI k\u00f3duje rozstup jednoduch\u00fdm sp\u00f4sobom: \u010d\u00edslo vydelen\u00e9 8 ud\u00e1va rozstup v osmin\u00e1ch palca. ANSI #40 m\u00e1 rozstup 40\/8 = 5\/8 \u00d7 25,4 = \u2026 po\u010dkajte, to nefunguje: 40\/8 = 5 a 5 osmin palca = 5 \u00d7 3,175 mm = 15,875 mm. Ale ANSI #40 m\u00e1 rozstup 12,70 mm, nie 15,875 mm. Skuto\u010dn\u00e9 pravidlo je, \u017ee \u00favodn\u00e1 \u010d\u00edslica (\u010d\u00edslice) predstavuje rozstup v osmin\u00e1ch palca, kde \u010d\u00edslo pred koncovou nulou (pre re\u0165aze s p\u00e1rnym rozstupom) je ozna\u010denie rozstupu.

Re\u0165az #25 sa riadi rovnak\u00fdm pravidlom: \u201e2\u201c = 2\/8 palca = rozstup 6,35 mm. Toto k\u00f3dovanie je konzistentn\u00e9 pre \u0161tandardn\u00fa s\u00e9riu, ale rozde\u013euje sa pre ozna\u010denia s \u0165a\u017ek\u00fdmi s\u00e9riami (pr\u00edpona H), dvojrozstupov\u00fdmi (predpona 2xxx) a viacpramenn\u00fdmi (pr\u00edpona po\u010dtu prame\u0148ov) re\u0165azami, ktor\u00e9 pou\u017e\u00edvaj\u00fa odli\u0161n\u00e9 konvencie.<\/p>\n<\/div>\n
