The following is a list of the values of many widely-used physical units, expressed in SI units in easily-pasteable form. Some of the values below are taken from the Gnu Scientific Library, which in turn takes its values from Mohr, Taylor & Newell (2008). Others, such as the lightyear and the parsec are derived from these values. Others are less precisely defined.
