Vietnamese units of measurement - Wikipedia

HistoryLengthAreaVolumeWeightTimeCurrencySee AlsoOriginally, many thước of varying lengths were in use in Vietnam, each used for different purposes. According to Hoàng Phê (1988), the traditional system of units had at least two thước of different lengths before 1890, the thước ta (lit. "our ruler") or thước mộc ("wooden ruler"), equal to 0.425 metres (1 ft 4.7 in), and the thước đo vải ("ruler for measuring cloth"), equal to 0.645 metres (2 ft 1.4 in). According to historian Nguyễn Đình Đầu, the trường xích and điền xích were both equal to 0.4664 metres (1 ft 6.36 in), while according to Phan Thanh Hải, there were three main thước: the thước đo vải, from 0.6 to 0.65 metres (2 ft 0 in to 2 ft 2 in); the thước đo đất ("ruler for measuring land"), at 0.47 metres (1 ft 7 in); and the thước mộc, from 0.28 to 0.5 metres (11 in to 1 ft 8 in).

High-voltage direct current - Wikipedia

High Voltage TransmissionHistoryComparison with ACCostsConversion ProcessConfigurationsCorona DischargeApplicationsAdvancements in UHVDCFurther ReadingHigh voltage is used for electric power transmission to reduce the energy lost in the resistanceof the wires. For a given quantity of power transmitted, doubling the voltage will deliver the same power at only half the current. Since the power lost as heat in the wires is directly proportional to the square of the current, doubling the voltage reduces the line losses by a factor of 4. While power lost in transmission can also be reduced by increasing the conductor size, larger conductors are heavier and more expensive. High voltage cannot readily be used for lighting or motors, so transmission-level voltages must be reduced for end-use equipment. Transformers are used to change the voltage levels in alternating current(AC) transmission circuits. Transformers made voltage changes practical, and AC generators were more efficient than those using DC. These advantages led to early low voltage DC transmission systems being supplanted by AC systems around the turn of the 20th century. Pra...Get price
