Tola

An Ancient Indian unit of measure that is now standardised as 180 troy grains (11.663 8038 grams) or exactly 3/8 troy ounce. Although it had been in use for considerably longer, the tola was adopted as the base unit of mass for the British Indian weights and measures system in 1833. Although widely replaced by the metric system, the tola is still a popular denomination for gold bullion bars in India, Pakistan and Singapore.
