Answer:

%The history of measurement systems in India begins in early Indus Valley Civilisation with the earliest surviving samples dated to the 5th millennium BCE.[1] Since early times the adoption of standard weights and measures has reflected in the country's architectural, folk, and metallurgical artifacts.[1] A complex system of weights and measures was adopted by the Maurya empire (322–185 BCE), which also formulated regulations for the usage of this system.[2] Later, the Mughal empire (1526–1857) used standard measures to determine land holdings and collect land tax as a part of Mughal land reforms.[3] The formal metrication in India is dated to 1 October 1958 when the Indian Government adopted the International System of Units (SI).[4]
