The SI unit for power is the Watt, the most commonly derived unit is for electrical power definition, which is the Kilowatt.
Water flow is measured in liters per second in the SI system.
The base unit of voltage is the volt, a combined unit meaning joules per coulomb.AnswerThe SI unit for voltage is the volt (symbol: V), which is a derived unit -not a base unit. There are seven base units in the SI system: metre, kilogram, second, ampere, candela, kelvin, and mole. SI units which are not base units are termed 'derived units'.
The reason is probably a practical one. Many scientist like to compare data internationally and many SI units are relatively practical, and, they are used all around the world. In this way, although in everyday life US Americans use their own measures, in scientific life they use SI units. In this way the scientific community can compare data all around the world.
Nobody "discovered" it. It's a natural unit in the cgs system, since it's the simplest energy unit expressed in the base units of that system. In SI, it's deprecated in favor of the joule; 1 erg = 100 nJ.
Metrics and SI units are commonly used by scientists. The SI system is worldwide and so everyone uses it. So a scientist across the world can under stand it.
SI system of measurement uses kilograms
the si system of units
No, pounds and inches are not part of the SI (International System of Units). The SI system uses kilograms for mass and meters for length.
The SI
Most of the world uses the metric system for measurement. The main units used outside of the U.S.A. is the metric system or SI (System Internationale).
The full French name of SI is Systeme International d'Unites, usually abbreviated to Systeme International. The English translation of SI is the International System of Units, commonly referred to as the Metric System..
Only three countries still cling to the "English" system, whereas the whole world uses metric. The SI units were established in 1960 as part of a review of the metric system used at the time; it uses metric units because it is the current version of the metric system.
The relevant SI bases are MKS.Length: cgs system uses centimetre, MKS uses metre = 100 centimetres. Mass: cgs system uses grams, MKS uses kilogram = 1000 grams. Time: they both use seconds.
Romania, like most countries, uses the SI system of measurement.
New Zealand uses the SI system of measurements for trade, and a decimal system of currency.
The system used in physics - and in fact in most of science - is called the SI, which is short for International System in French.
