## K : Sound and Vibration Definitions, Terms, Units, Measurements ...

**k : kilo** a SI prefix = 1000

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

**kilo : k** a SI prefix = 10^{3} : 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·m**^{2}·s^{-2} energy or work.

The derived SI unit is the Joule J :
1 kg·m^{2}·s^{-2} = 1 J = 1 N·m = 1 W·s = 10^{7} ergs

**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** measurement of force - the derived SI unit is the Newton

1 kg·m·s^{-2} = 1 N = 10^{5} dynes

**kilogram per cubic metre : kg/m**^{3} is Density

**kilogram per metre per second squared : kg/m/s²** measurement of pressure - see the Pascal.

1 kg/m/s^{2} = 1 pascal (Pa) = 1 N/m^{2} = 1 J/m^{3} = 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.
