The kilogram or kilogramme (SI symbol: kg), also known as the kilo, is the base unit of mass in the International System of Units and is defined as being equal to the mass of the International Prototype Kilogram (IPK), which is almost exactly equal to the mass of one liter of water. The avoirdupois (or international) pound, used in both the Imperial system and U.S. customary units, is defined as exactly 0.45359237 kg, making one kilogram approximately equal to 2.2046 avoirdupois pounds.
In everyday usage, the mass of an object given in kilograms is often referred to as its weight, which is the measure of the gravitational force—or heaviness—of an object. Weight given in kilograms is technically the non‑SI unit of measure known as the kilogram-force. The equivalent unit of force in the avoirdupois system of measurement is the pound-force. In strict scientific contexts, forces are typically measured with the SI unit newton.
The kilogram is the only SI base unit with an SI prefix as part of its name. It is also the only SI unit that is still directly defined by an artifact rather than a fundamental physical property that can be reproduced in different laboratories. Four of the seven base units in the SI system are defined relative to the kilogram so its stability is important.

Volen Nikolov Siderov (Bulgarian: Волен Николов Сидеров) (born 19 April 1956) is a Bulgarian politician and chairman of the nationalist party Attack. He is famous for his hard-line attitude towards minorities in Bulgaria, especially Roma and Turks.
Siderov was born in 1956 in Yambol, Bulgaria. He received an undergraduate degree in Applied Photography in Sofia, and before the fall of Communism in 1989, worked at the National Literature Museum as a photographer.
After the fall of Communism, Siderov became a member of the newly-established Movement for Human Rights. During the fall of 1990, he became the editor-in-chief of Democracy (Bulgarian: Демокрация), the official newspaper of the Union of Democratic Forces (Siderov played a major role in establishing the paper as the official publication of the right-wing party).
In 1992, he was fired from the newspaper and put an end to all relationships with his political partners. In 1995 Siderov led the PR Center of the Bulgarian Socialist Party during local elections in capital Sofia. Later he unsuccessfully tried to get a place in the lists for MP in the ex-king Simeon II's party NDSV. At one point he was appointed deputy editor-in-chief of Monitor, a newspaper of a political orientation that could be described as nationalist and conservative. In 2000, Siderov was presented with the award of the Union of the Bulgarian Journalists. Later, he was fired from Monitor as well, and he came to be the host of Attack, a talk show on the Bulgarian cable TV channel "SKAT". In it, he chastised the perceived corruption of the Bulgarian political establishment and blamed Bulgaria's poor economic condition on the ethnic minorities.[citation needed] In 2002 Siderov was invited to a controversial anti-globalisation conference in Moscow where he rubbed shoulders with people like Ahmed Rami and David Duke.
