The new International System of Units (SI)
03.04.2017
The metrological background factors and implications from this revision of the SI form one element. Providing information on this reform to the broadest possible spectrum of experts, to schools and universities, and to the general public forms another element. It is this dissemination of information that PTB takes very seriously, developing a range of publications for its different target groups and several event formats for this complex subject. These publications can be downloaded from http://www.ptb. de/cms/en/research-development/research-on-thenew- si.html or ordered from the Press and Information Office. This website also contains all available PTB info sheets in all matters related to the new SI.
