WebIPTS-68: This is an international standard from 1968 where R100/R0=1.3850 that was used by the JIS from 1989 to 1997, but currently it is not in use. ITS90: An international … WebToday's instruments typically record in the ITS-90 scale, but some old datasets will be in the IPTS-68 scale. T90fromT68() converts from the IPTS-68 to the ITS-90 scale, using Saunders' (1990) formula, while T68fromT90() does the reverse. The difference between IPTS-68 and ITS-90 values is typically a few millidegrees (see …
