Chemists' Calendar

The third new edition of the Chemist's Calendar (to be precise, it is the 121st) is tailored to the current needs of the experimental chemist. With the legal introduction of SI units, chemists are often required to convert to SI units (or from British and US units). Therefore, a table with the corresponding conversion factors has been included at the beginning of the volume. Since it was not possible to account for all the often quite unusual units used abroad, a general method is also provided for how users can help themselves in such cases. Many individual tables have been converted to SI units. To make the new edition as practical as possible, where older units are still commonly used, these are included in parentheses (vapor pressures in T).
