K
k- : see kilo.
kHz : kilohertz : 1000 Hz.
kilo : k : SI prefix = 103 see other SI Units
kilogram : kg : the base unit of mass in the SI and MKS versions of the metric system. The kilogram is defined as the mass of the standard kilogram.
1 kg = 1000 g ~ 2.204 pounds
kilogram metre : kg·m :
1:- a metric unit of work or energy equal to 9.806 65 joules (J).
2:- a metric unit of torque equal to 9.806 65 newton meters (N·m).
kilogram metres squared per second squared : kg·m2·s-2 : energy or work, the derived SI unit is the Joule J
1 kg·m2·s-2 = 1 J = 1 N·m = 1 W·s = 107 ergs
kilogram metres per second : kg·m/s : the SI unit of momentum.
1 kg·m/s = 1 N·s
kilogram metre per second squared : kg·m/s² : measurement of force - the derived SI unit is the Newton :
1 kg·m·s-2 = 1 N = 105 dynes
kilogram per cubic metre : kg/m3 : density
kilogram per metre per second squared : kg/m/s² : measurement of pressure - see the Pascal.
1 kg/m/s2 = 1 pascal (Pa) = 1 N/m2 = 1 J/m3 = 10-5 bar
kilohertz : kHz : 1000 Hz.
kilopascal : kPa : a common metric unit of pressure.
1 kilopascal = 1000 pascals (Pa) = 10 millibars (mb)
