A kilogram was defined as 1 L of liquid water at 4 Celsius.
The kilogram is the base SI unit of mass and cannot be simplified any further.
Its symbol is kg.
In 1795, in France the gram was originally defined as "the absolute weight of a volume of water equal to the cube of the hundredth part of the meter, at the temperature of melting ice." A kilogram is of course simply 1,000 grams.
In 1889, the kilogram was more precisely defined by a benchmark called the International Prototype Kilogram or "IPK", made from platinum alloy. It and 6 replicas are stored in an environmentally monitored safe in the basement of the French International Bureau of Weights and Measures(BIPM) outside Paris.

What does kilograms equal too?
Originally a kilogram was defined as the mass of 1 litre of water:pure water at a pressure of one bar and a temperature of 4 deg Celsius (when it has its maximum density). However, it was subsequently redefined so that now it is the mass of a standard (or prototype) kilogram which has a mass of 1.000025 litres.
SI unit mass?
The SI unit for mass is the kilogram (kg). It is defined by the mass of the international prototype of the kilogram, which is a platinum-iridium alloy cylinder stored in France.
What is the scientific unit of mass?
The scientific unit of mass is the kilogram, symbolized as "kg." It is defined as the mass of the international prototype of the kilogram, a platinum-iridium cylinder kept at the International Bureau of Weights and Measures in France.
The kilogram is the basic metric unit of?
The kilogram is the basic metric unit of mass. It is defined as the mass of a specific platinum-iridium alloy cylinder kept at the International Bureau of Weights and Measures in France.
Which measure in the metric system is defined by using an object for a referent?
The kilogram is the measure in the metric system that is defined using an object for a referent. It was previously defined by a physical object known as the International Prototype of the Kilogram, but is now defined in terms of a fundamental constant of nature called Planck's constant.
A kilogram was originally defined as the mass of?
When the metric system was originally devised, the kilogram was defined so that 1,000 cubic centimeters (1 cubic decimeter) of pure water has a mass of exactly 1 kilogram.
What is -gram?
The gram is a metric unit of mass. It was originally defined as the mass of 1 cm3 of pure water at the temperature of melting ice, but is now defined as 0.001 of the mass of a kilogram.
What is the gram?
The gram is a metric unit of mass. It was originally defined as the mass of 1 cm3 of pure water at the temperature of melting ice, but is now defined as 0.001 of the mass of a kilogram.
What is equal to the mass of kilogram?
A liter of water has approximately a mass of one kilogram.
What does kilograms equal too?
Originally a kilogram was defined as the mass of 1 litre of water:pure water at a pressure of one bar and a temperature of 4 deg Celsius (when it has its maximum density). However, it was subsequently redefined so that now it is the mass of a standard (or prototype) kilogram which has a mass of 1.000025 litres.
How is mass defined in physics?
Mass is a measure of a body's inertia in which the SI unit is the kilogram.
SI unit mass?
The SI unit for mass is the kilogram (kg). It is defined by the mass of the international prototype of the kilogram, which is a platinum-iridium alloy cylinder stored in France.
What is the scientific unit of mass?
The scientific unit of mass is the kilogram, symbolized as "kg." It is defined as the mass of the international prototype of the kilogram, a platinum-iridium cylinder kept at the International Bureau of Weights and Measures in France.
Is kilogram a derived unit?
Yes, the kilogram is a base unit in the International System of Units (SI) and not a derived unit. It is the unit of mass and is defined by a physical prototype known as the International Prototype of the Kilogram (IPK).
Half of a kilogram of butter has a mass of what?

1000 grams is ONE what?
1,000 grams is one kilogram in the International System of Units (SI). The kilo prefix means one thousand, so a thousand grams is a kilogram. Originally defined as the mass of a cubic decimeter (liter) of water, the kilogram is today standadized as the mass of a platinum-iridium international prototype kept at the International Bureau of Weights and Measures (Bureau International des Poids et Mesure, near Paris, France). A one-kilogram mass has an Earth weight of about 2.2 pounds.
The kilogram is the basic metric unit of?
The kilogram is the basic metric unit of mass. It is defined as the mass of a specific platinum-iridium alloy cylinder kept at the International Bureau of Weights and Measures in France.
