Because we are frequently asked about on-line unit conversions, we provide
links for the convenience of users to several non-NIST sources. Under no
circumstances does NIST endorse or warrant their values. Official
values of conversion factors are available in the Appendix of NIST Special
Publication 811 in html
or pdf form. This document is
also available free of charge by mail.
