* The unit name ''megagram'' is rarely used, and even then typically only in technical fields in contexts where especially rigorous consistency with the SI standard is desired. For most purposes, the name ''[[tonne]]'' is instead used. The tonne and its symbol, "t", were adopted by the CIPM in 1879. It is a non-SI unit accepted by the BIPM for use with the SI. According to the BIPM, "This unit is sometimes referred to as 'metric ton' in some English-speaking countries."<ref>''Non-SI units that are accepted for use with the SI'', [https://www.bipm.org/en/publications/si-brochure/ SI Brochure: Section 4 (Table 8)], BIPM</ref>
