SI base unit SI base unit The International System of Units (SI) defines seven units of measure as a basic set from which all other SI units can be derived. The SI base units and their physical quantities are the meter for measurement of length, the kilogram for mass, the second for time, the ampere for electric current, the kelvin for temperature, the candela for luminous intensity, and the mole for amount of substance. The SI base units form a set of mutually independent dimensions as required by dimensional analysis commonly employed in science and technology. The names and symbols of SI base
Notional amount inverse exchange-traded funds, have the unusual property that their notional changes every day: this is because they pay the compounded daily return, so it is as if one were re-investing each day's earnings at the new daily price: if one has an inverse ETF in an asset that goes down, one has more money, which one uses to short a cheaper asset, hence one's unit notional goes up, and conversely if the asset has gone up in value. See inverse exchange-traded fund for mathematical details. Notional amount The notional amount (or notional principal amount or notional value) on a financial
