  2. Newton-metre - Wikipedia

    en.wikipedia.org/wiki/Newton-metre

    141.6 in oz. The newton-metre or newton-meter (also non-hyphenated, newton metre or newton meter; symbol N⋅m[ 1 ] or N m[ 1 ]) [ a ] is the unit of torque (also called moment) in the International System of Units (SI). One newton-metre is equal to the torque resulting from a force of one newton applied perpendicularly to the end of a moment ...

    mole. amount of substance. cd. candela. luminous intensity. 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 ...

  4. Newton (unit) - Wikipedia

    en.wikipedia.org/wiki/Newton_(unit)

    0.224809 lbf. The newton (symbol: N) is the unit of force in the International System of Units (SI). It is defined as , the force which gives a mass of 1 kilogram an acceleration of 1 metre per second squared. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically his second law of motion.

  5. SI base unit - Wikipedia

    en.wikipedia.org/wiki/SI_base_unit

    A litre is one thousandth of a cubic metre. M ampere: A electric current "The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 × 10 −19 when expressed in the unit C, which is equal to A s, where the second is defined in terms of ∆ν Cs."

    The SI also defines 22 derived units and associated symbols: The hertz (Hz) is equal to one reciprocal second (1 s −1). The radian (rad) is equal to one (1). The steradian (sr) is equal to one (1). The newton (N) is equal to one kilogram-metre per second squared (1 kg⋅m⋅s −2). The pascal (Pa) is equal to one newton per square metre (1 N ...

  7. Metric system - Wikipedia

    en.wikipedia.org/wiki/Metric_system

    The metric system is a decimal -based system of measurement. The current international standard for the metric system is the International System of Units (Système international d'unités or SI), in which all units can be expressed in terms of seven base units: the metre (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol), and ...

  8. SI derived unit - Wikipedia

    en.wikipedia.org/wiki/SI_derived_unit

    The SI has special names for 22 of these coherent derived units (for example, hertz, the SI unit of measurement of frequency), but the rest merely reflect their derivation: for example, the square metre (m 2), the SI derived unit of area; and the kilogram per cubic metre (kg/m 3 or kg⋅m −3), the SI derived unit of density.
