Gold is often measured in Tola. It may seem unusual but Tola (Sanskrit: तोलकः; tolaka) is a traditional South Asian unit of mass. 1 Tola is standardized as 11.3398038 grams but most jewelers in Nepal count as only 10 grams. That is correct. 1 Tola Gold is equivalent to 10 grams of gold in the streets of Nepal.
1 Tola Gold = 10 Grams. of Gold
Here is the definition of Tola from Wikipedia:
The tola (Hindi: तोला; Urdu: تولا; Bengali: তোলা; tolā. from Sanskrit: तोलकः; tolaka) Punjabi ਤੋਲਾ, also transliterated as tolah or tole, is a traditional Ancient Indian and South Asian unit of mass, now standardised as 180 troy grains (11.3398038 grams) or exactly 3/8 troy ounce. It was the base unit of mass in the British Indian system of weights and measures introduced in 1833, although it had been in use for much longer. It was also used in Aden and Zanzibar: in the latter, one tola was equivalent to 175.90 troy grains (0.97722222 British tolas, or 11.33980925 grams).
The tola is a Vedic measure, with the name derived from the Sanskrit tol (तोलः root तुल्) meaning “weighing” or “weight”. One tola was traditionally the weight of 100 ratti (ruttee) seeds, and its exact weight varied according to locality. However, it is also a convenient mass for a coin: several pre-colonial coins, including the currency of Akbar the Great (1556–1605), had a mass of “one tola” within slight variation. The very first rupee (Urdu: رپيا; rupayā), minted by Sher Shah Suri (1540–45), had a mass of 178 troy grains, or about 1% less than the British tola.The British East India Company issued a silver rupee coin of 180 troy grains, and this became the practical standard mass for the tola well into the 20th century.
