k- : prefix = kilo.

kHz : kilohertz : 1 kHz = 1000 Hz = 1000 Hertz.


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 metres (N·m).


kilogram metre 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 metre 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)


Kinetic Energy : all moving things have kinetic energy. It is energy possessed by an object due to its motion or movement, measured in Joules.

Kinetic Sound Energy Density.
