The tonne (SI unit symbol: t) is a metric system unit of mass equal to 1000 kilograms. It is a non-SI unit accepted for use with SI. To avoid confusion with the ton, it is also known as the metric tonne and metric ton in the United States and occasionally in the United Kingdom. In SI units and prefixes, the tonne is a megagram (Mg), a rarely-used symbol, easily confused with mg, for milligram.

In the U.S., the National Institute of Standards and Technology supports the symbol "t" for the tonne. The abbreviation "mt" or "MT" is also used in the U.S.

The SI unit symbol for the tonne is "t". Abbreviations for "tonne" ("metric ton" and "metric tonne") include "T", "mT", "MT", and "mt" (especially in the combination "mmt" or "MMT" for "million metric tons"), and "Te" (particularly in the offshore and nuclear industries).^{[citation needed]} SI has no abbreviations for SI units, only symbols, and some of the abbreviations in use are actually SI symbols for other units: "T" is the SI symbol for the tesla and "Mt" is the SI symbol for megatonne.

Robert Matthew Van Winkle (born October 31, 1967), best known by his stage name Vanilla Ice, is an American rapper. Born in South Dallas, and raised in Texas and South Florida, Van Winkle released his debut album, Hooked, in 1989 through Ichiban Records, before signing a contract with SBK Records, a record label of the EMI Group which released a reformatted version of the album under the title To the Extreme. Van Winkle's single "Ice Ice Baby" was the first hip hop single to top the Billboard charts.

Although Van Winkle was successful, he later regretted his business arrangements with SBK, which had paid him to adopt a more commercial appearance to appeal to a mass audience and published fabricated biographical information without his knowledge. After surviving a suicide attempt, Van Winkle was inspired to change his musical style and lifestyle. While later albums by Van Winkle haven't charted or featured much radio airplay because of their less mainstream, rock-oriented sound, Vanilla Ice has had a loyal underground following. In 2009, Van Winkle began hosting The Vanilla Ice Project on DIY Network. His latest album WTF – Wisdom, Tenacity & Focus was released in August 2011. Van Winkle is currently signed to Psychopathic Records.
