The 17th General Conference on Weights and Measures Ends. The conference passed a resolution defining a meter as the distance traveled by light in vacuum during a time interval of about three hundred millionth of a second. Before this, the meter or metre was assigned several different definitions. In 1793, it was defined as one ten-millionth of the distance between the Earth's Equator and the North Pole. In 1960, it was once again redefined by the 11th General Conference of Weights and Measures as equal to “1650763,73 wavelengths in vacuum of the radiation corresponding to the transition between the levels 2p10 and 5d5 of the krypton 86 atom.”

Provisional Government of Free India Declared by Subhas Chandra Bose. Bose, an exiled Indian nationalist and a key figure in the Indian Independence Movement declared the creation of Azad Hind or Free India during a mass rally in Singapore. Netaji (leader), as he was fondly called by his followers, was unanimously declared as the Head of State, Prime Minister, and Minister for War of the new government. The government-in-exile did not have any territory to govern until Japan gave them the Andaman and Nicobar Islands, occupied by the Japanese in 1942, to run. A few days later after declaring the existence of Azad Hind, the provisional government joined the Second World War by declaring war on the Allies.
