The history of measurement systems in Pakistan begins in early Indus Valley civilization with the earliest surviving samples dated to the 5th millennium BCE. The Mughal empire (1526–1857) used standard measures to determine land holdings and collect land tax as a part of Mughal land reforms. British units of measurement were adopted in South Asia as first the East India Company and later colonial rule gained foothold. The formal Metrication in Pakistan is dated to October 1967 when the Government of Pakistan adopted the International System of Units (SI)
