WebMar 22, 2007 · An easy way to convert metric surface call outs to standard U.S. ones (rms) is to mentally multiply the metric value by 40. For example, 1.6 = 63 rms, 3.2 = 125 rms, and 6.3 = 250 rms. And for metric "triangle" callouts you can approximate one triangle = 250 finish, two triangles = 125 finish, and three triangles = 32 to 63 finish. WebNov 26, 2024 · For this reason, when we see 'grades' in charts like the one on this page and in ISO 1302, the issue becomes whether a given finish is smooth enough to qualify for a given grade. Since an Ra 7.4-7.8 is rougher than an Ra of 6.3, such a surface does not qualify as an N9, but only as an N10. Luck & Regards,
