Exempel på hur du använder SI i en mening

• The candela (symbol: cd) is the unit of luminous intensity in the International System of Units (SI).
• The erg is not a part of the International System of Units (SI), which has been recommended since 1 January 1978 when the European Economic Community ratified a directive of 1971 that implemented SI as agreed by the General Conference of Weights and Measures.
• In the International System of Units (SI), the unit of measurement of momentum is the kilogram metre per second (kg⋅m/s), which is dimensionally equivalent to the newton-second.
• The unit of radioactivity from the System International of units (SI system) is the becquerel (Bq) defined as the radioactive decay or disintegration of one radionuclide per second.
• The SI comprises a coherent system of units of measurement starting with seven base units, which are the second (symbol s, the unit of time), metre (m, length), kilogram (kg, mass), ampere (A, electric current), kelvin (K, thermodynamic temperature), mole (mol, amount of substance), and candela (cd, luminous intensity).
• The SI base units form a set of mutually independent dimensions as required by dimensional analysis commonly employed in science and technology.
• SI coherent derived units involve only a trivial proportionality factor, not requiring conversion factors.
• The SI base unit of time is the second, which is defined by measuring the electronic transition frequency of caesium atoms.
• It is often quantified numerically using SI derived units (such as the cubic metre and litre) or by various imperial or US customary units (such as the gallon, quart, cubic inch).
• Force, and thus thrust, is measured using the International System of Units (SI) in newtons (symbol: N), and represents the amount needed to accelerate 1 kilogram of mass at the rate of 1 meter per second per second.
