k : kilo a SI prefix = 1000

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

kilo (k) an 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 cubed (kg·m2·s-3), power and the derived SI unit is the watt (W), see sound power.

kilogram metre squared per second squared (kg·m2·s-2), energy or work.
The derived SI unit is the joule (J)

kilogram metre per second (kg·m/s) is the SI unit of momentum. 1 kg·m/s = 1 N·s

kilogram metre per second squared (kg·m/s²), a measurement of force
1 kg·m·s-2 = 1 N = 105 dynes, the derived SI unit is the newton

kilogram per cubic metre (kg/m3), the SI unit of densitysound energy density

kilogram per metre per second squared (kg/m/s²), a measurement of pressure

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)


Kinematic Field Quantity, acoustic examples, vibration velocity, particle velocity.

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