You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.
question:
original question: Which measurement system use [Kilogram] as mass unit?
answer: international system of units
answer type: Measurement System.
auxiliary information: The kilogram or kilogramme, 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 of the Kilogram. The gram, 1/1000th of a kilogram, was originally defined in 1795 as the mass of one cubic centimeter of water at the melting point of water. The original prototype kilogram, manufactured in 1799 and from which the IPK is derived, had a mass equal to the mass of 1.000025 liters of water at 4 C. 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. Three other base units in the SI system are defined relative to the kilogram, so its stability is important. The International Prototype Kilogram was commissioned by the General Conference on Weights and Measures under the authority of the Metre Convention, and is in the custody of the International Bureau of Weights and Measures who hold it on behalf of the CGPM.

The [Kilogram] is used as a measurement of mass in what system?

auxiliary information: Datsun is an automobile brand owned by Nissan. Datsun's original production run began in 1931. From 1958 to 1986, only vehicles exported by Nissan were identified as Datsun. In 1986, Nissan phased out the Datsun name but re-launched it in 2013 as the brand for low-cost vehicles manufactured for emerging markets. In 1931, Dat Motorcar Co. chose to name its new small car "Datson", a name which indicated the new car's smaller size when compared to the DAT's larger vehicle already in production. When Nissan took control of DAT in 1934, the name "Datson" was changed to "Datsun", because "son" also means "loss" in Japanese and also to honor the sun depicted in the national flag. Nissan phased out the Datsun brand in March 1986. The Datsun name is most famous for the 510, Fairlady roadsters, and later the Fairlady coupes.
